A downloadable game for Windows

"We heard a rumor about a mansion on the outskirts of town...

They say there is a monster that lives there."

What is Ao Oni R?

The 'R' in Ao Oni R can stand for a lot of things - such as reboot, remake, or retelling, but at its core it is a labor of love. It is the Ao Oni experience everyone knows and loves, having been rebuilt from the ground up in RPG Maker VX Ace to expand upon the original games ideas while giving it a fresh coat of paint. New story elements and areas, graphics, music, sound, puzzles, expanded character backgrounds as well as multiple endings exist in Ao Oni R while still keeping the principles of the original, such as a low amount of dialogue when possible and the possibility of a fast play through.

Hide or die!

You are never alone! The Oni always has a chance of appearing!  Hide from the immortal demon in lockers, toilet stalls and jail cells, or banish it temporarily using the new item, agrimony.

Solve the mystery!

All puzzles from the classic game return, as well as several new ones! New areas, along with 6 different endings and the ability for any character to die makes for multiple runs!

An expansive cast!

All the cast have been rewritten to include a wide variety of backgrounds and emotions, each with their own agenda and goals that can be revealed during the game. Anna and Shun also make their video game appearance.


As much as I tried, I have probably failed to squash all the bugs. If you spot any, let me know in the comments. Remember to save constantly, just in case!

Pretty good game! Keep getting stuck in the Annex though, because I can’t see any statue to push down the stairs, and I haven’t found any guides online to help. The puzzles are pretty hard, which is a good thing! And I love that the remake/reboot/retelling has updated graphics and additional content. It’s always nice to see a developer still paying attention to a game after its initial release. 

Nevermind! I didn’t think of grabbing the red gem after using it to open the case. 

Anyway, this seems like a game that could easily hide a lot of secrets. Any chance I could get a list? I’m a completionist who likes to experience everything a game has to offer. 

THAT WAS THE BEST!!! I want a translate to turkish this game

The blue key is still a softlock. Me and my bf were playing and we already put the key in the lock, so we can't pick it back up or reuse the rope. We can't do anything to progress and we can't put the key back because it's not in our inventory. What should we do?

I have the same issue... I'm still in the end of the game, and I'm stucking now with this softlock.

Any solution? Thx

I think I get what you mean now. You mean at the exit with the three doors? If the rope was placed in solitary, it should always be able to be collected/climbed or climbed. There should be no way to get trapped in that room unless I didn't update it properly. Try this file - it's the one I was editing the game with so it may be a bit of a mess. You can copy your save game file over by going to the main folder and copying Save01.rvdata2, Save02.rvdata2 etc to the new folder. https://www.mediafire.com/file/67r05rmez47vevr/Ao+Oni+R.exe/file

If it still does it I'll see if I can make some adjustments.

Many Thx buddy, but doesn't work... I can't get back neither rope nor blue key. Same issues... :-/

Alright, try this one. I made it so you can always climb the rope and have to collect it from the top instead of solitary, and I also made it so you can take back any of the three blue keys in the exit area as long as you haven't used all three there. https://www.mediafire.com/file/z9cagatjnfld8b1/Ao_Oni_R.exe/file

Nice ! <3 It does work fine! Now I can finish this beautiful game. <3 <3 <3

Sorry... I'm back again :-/

When I got back the rope+hook, I managed to get the Study Key in the Cells but can't...

I've just re-install old version of Ao Oni R (1.19b) with my new save (Rope+hook in my backpack) and then I can reach it with the rope!

Many Thanks!

pretty nice recreation of the game. for some reason though, i feel like it would be a funny easter egg if the monster had oneyng's head on

Wait, so is the entire game fully remade?

hello when i open the game there is no audio. so i want to know how to fix that so i can play this game

Not sure about that, did you install the RTP first? Also it could be muted in the volume mixer or not enabled in the debug menu. Press F1 when the game is running to bring up the debug menu.

thanks for the help. I'm not use to having to check the debug menu when I play games that I download. so I really appreciate the help and I can't wait to play this awesome looking game.

I will run this on windows xp

When the DLCS will be released?

How many characters will be in the game? Will there be more characters, like Honoka?

Great Game but i have a question for you. How can you unlock the room near the bedroom in the second floor and the room near the laundry? I played the game 4 times but still cant unlock it..

Second floor is for when you start a new game plus (load up a completed game save) which gives the ability to change costumes, and the laundry is simply a locked door/back door to outside (not used for anything)

On a second note - sad that your version didn't get much attention. I wish more popular youtubers played it.

Surprisingly my video on my channel is nearing 30k views, had 2.5k downloads so it was pretty successful in my opinion. I had another 2k downloads before I didn't know how to use this site properly and replaced the download so it's around 4-5k downloads including gamejolt.

So yeah I completed the game :D

And what can I say... it was amazing. Challenging puzzles, interesting story and multiple endings (3 done, 2 more to go). On my first try I got Oxalis and D rank D:

5 stars. By the way another question for the puzzle:






Last part of the game, that one with shadows where you had to put statues and light. There were 3 shapes that translated to the code -045.

One is missing. How do I know the first digit?

In the solitary room where one of the blue keys are (that shuts the door when taken) on the table. Use the lighter to see the number.

thanks for answer

(1 edit)

[Yes, I am THAT dumb.]

The puzzles in this one are quite hard lol.
I wanted to ask - is there like text explanation of all puzzles? Like I just stumbled upon the clock puzzle and [Spoilers ahead]




I am kinda confused. The book that lists deaths have 0, 3, 5, 1 numbers colored. After thinking for a bit I checked your walkthrough and the answer is 03:15... Did I missed some note that explains the order?


It's not quite every puzzle, but should help.


Piano - Combine Handkerchief and Soap and wipe the piano, avoid the Oni that will drop down and then go back and investigate. Looking at the message of the sun and moon the code it is the third number rotating while the second sits still, then the third number passes it only as its equal - only the second and third numbers are used - the third number rotates while the second is the same and then the third is used again only without rotating, then the final number would be what wasn't used.

Shrine - Use the Red Gem to get the Old Key. Take it back after.

Clock Room - The order of the red numbers are based on the dates of the deaths in order.


The lighter can make hidden items shimmer when near them on the shelves in the starting room. The cage room should have its light lit and door closed, then look at the right of the door for the code to the safe.


Head to the attic and get the lighter fluid, then back down to the 1F and into the kitchen and use the lighter, grabbing the rotten meat from the fridge and push the dumbwaiter button to send it to the 2F. Grab the guest room key from the dumb waiter and light bulb from the lamp.

The 2F outside balcony has the code from Jeff for his room box to get powder, as well as the grams needed for the explosive. 1.25 The fireplace can be lit and the doll burned to get the Yellow Gem, and the attic will now have a number etched in you need. The doll is in the North Hall left room (Jeff's Room) and one of its eyes sparkle.

In the North Hall right side door, put the Yellow Gem into the doll there and turn off the light, then take the doll head and replace it with the lightbulb to reveal a hidden door. Back in Jeff's room, use the doll head to reveal the safe and then the code from the attic to open the safe and get the basement key.


Move the shelf to the left of the door to reveal a panel. Use the star screw driver to open it and solve the puzzle (third, first, second) to restore power. Also get the picture book on the shelf and check it for the bookmark.

Use the flathead on the door panel to undo it, then use the bookmark to figure out the door code (red, green, grey, blue)

Use vinegar on the red key from the tub room (drain the tub, push it from the top) to get the iron gate key and proceed down to the basement. Check the disc and follow its pattern to push the portraits correctly (red, yellow, yellow, blue, yellow, red) to get metal stick. Combine it with the disc to get the catacombs key.

In the catacombs grab a bunch of gun powder (you can measure it later in Jeff's room with his scales and what the note said) Combine the powder and gun powder for explosive.

OLD BUILDING (Great to explore and figure out this area on your own)

Medical Room - Push the statue and torch from the exit into the room, gold statue is left, silver right and use the flame on each side and take note of the sides of each shape.

Thank you so much!

Love the game, hope to see more from you in the future :3

I might download this game and stream it on Twitch sometime. Never streamed Ao Oni before, but I might play this as a good return!

Have fun, just try to ignore my crappy spelling and grammar lol

Aight lol

I absolutely loved this game. My only problem with it is that... It's kinda way too easy to save everyone! 

It should be challenging to save all the characters. For example, it's actually kinda hard to save Mika, specially if you played the original and go investigate the 2th floor after her scream. It's very well done, in my opinion!

Everyone else, tho... They just die if you want to! 

Anyway, are you still working on the game? :3 

That was what I was going for, to give the player the freedom to decide. 

Mika was an odd case since in the original she died and became an oni in the basement, so that created ~6 conditions just by the time you reached the basement. The other deaths were actually placeholders but I really liked how they flowed towards the end of development that I kept them. It also burned me out on how buggy her conditions become with all the events that it wore me down trying to fix them.

As for the game, I've tried to work on the DLC and restarted several times from scratch, but I'm just having trouble getting it to a point I like, so I'll probably not release it (sorry) 

On the plus side, I have a first draft design completed of a new horror game which I'm happy with as well as two very early survival horror games and a short oc horror titled Floss. I've also been toying with ideas to start an R version of Ao Oni School Nightmare, but that's just thoughts really. 

Ohhh, that's really interesting! I would love to play an remake of Ao Oni S! Which characters would be in the game, you think?

Anyway, that makes sense to me. I thought you were going for something like Until Dawn, where saving everyone is hard lol 

But anyway, thanks for this incredible game! :3

What about an Ao Oni 2 R?

Since Ao Oni 2 is a mobile game, the controls are kinda awful, plus the game is on portrait for some reason.

Idk, I think it would be cool to see.

A lot of RM Chinese games nowadays. :/

I always have the right amount of powder but nothing happens afterwards, I can not mix it, I do not know if it's a bug or it's something I'm doing wrong.

Will you add South Park Mode?

Stuck on statue puzzle in the old building and need help. Can you tell me about the gold and silver statues?


Push the statue and the torch from the exit area into the medical room. put them on the correct color and push the torch on either block below it.

I really love playing this game. But I just have a problem, whenever I soft reset with F12, the next time I try to load  a save file or start a new game, the game will close because of an error that says "bitmap disposed"?

Sorry, that's a little set back due to the lighting engine that was used, but it was a good trade off. You'll just have to close and reopen the game or load from the menu in game.

Ahh this seems so cool! I look forward to playing this.

I'm actually in the middle of reading the Ao Oni novels, so it excites me to see a game that will feature Shun and Anna! 

Stuck on statue puzzle in the old building and need help. Can you tell me about the gold and silver statues?

okay so, im stuck in this weird gun powder puzzle where you have to measure it to a suitable amount, and i just cant understand it, can someone please help

Easiest way is to put only one powder on the scales and then fiddle with the weights until it says both are equal. 

Once you know how much a single gunpowder weighs you can then use basic math to measure out what the note on the 2F balcony wants you to measure.

okay, so i dont know if this is a bug or a glitch, but in the old building when you have to combine a rope with a hook  in order to get a blue key and climb out, i discovered that before doing that i had to use the rope and the hook to get the study key thats stuck in one of the jailcells, but the thing is, i used the rope and the hook  to get the blue key in the basement before getting the study key, and now i cant take back the rope and the hook to advance. so now im stuck and cant do anything unless a replay the entire game again.

The bug I believe is the same as mentioned below, I recently hotfixed it. Also If you stand in front of the area where you picked up the blue key and then select it from the inventory, you can place the key again to unlock the door.

I think I've found a bug or at least a softlock in the game. If you use the rope and hook in the solitary room and deposit the blue key prior to getting the key within the cells, you can't pick up the hook and rope without getting trapped. Beyond that, if you choose to collect the rope and hooke, you get locked in the room, unable to rope up again or open the door. This is the only game breaking bug I've seen up to this point with some collision errors but those aside this is a fantastic remake!

Oh god, just when I thought I was finally done with the bugs lol. Thanks for the report, I'll look over it in the next day or two. I'm glad you like the game, it means a lot.

I am at the part where you can go into the basement, yet everytime Mika screams and gets killed. How do I get Mika to, y'know, not die? It's really bugging me and I want to complete the game with a perfect ending.

(1 edit)

It has some bugs, which I'm in the process of fixing but, the way it works is:

You need to ignore the scream and just enter the basement, but there are conditions to it.

-When you hear Mika scream, checking the second floor in the room will always get her killed
-If you enter the basement after the scream without a) having Anna alive, or b) getting the compression kit, then Mika will die
-If Anna is alive, but you don't get Mika the compression kit, she will survive with Anna's help _but_ die towards the end of the game because of her ankle in an alternate/hidden death (my favorite death)

In short, to save Mika, you need to get her the compression kit for her ankle, which can be found in the left hall bathroom where the hiding spot/toilet is and just continue entering the basement after you hear the scream.

Brilliant! All checks out! Thanks so much, and happy new year!

Ignore the scream? So how did our character showing up cause her death? Did our yummy life force lead it to her?

Ok i'm on the basement part and i got a red gem, i don't know what the fuck to do with it.  I think i'm stuck, help anyone?

Sorry for the late reply, doubt you're still stuck by now but if you are:

Red Gem goes into the case in the room next to the basement door (undo the panel with the screwdriver). That will get you the key for the Rumpus Room on the third floor of the mansion.

I have no idea on how to make explosive chemical. I have Gun powder and Powder

(1 edit)

You need the correct amount of gun powder measured at the scales in the Doll Makers room (North Hall of the Annex)

The amount you need is revealed on the 2F Balcony of the Annex in a note. (through the Dining Room)

It's just a matter of figuring out what each chunk of gunpowder is worth.

Thank you so much

I just can't find the way to get the perfect ending... I know it's probably connected to the spell somehow, but I still can't find it... It was a great game regardless! I was a big fan of the original game, but it always bugged me how there was no option to save the gang. Now I can finally make the dream come true :^) This is also beyond amazing for a fan game, I'd even go as far as saying it's better than the original. Bigger map, more story, alive friends... What more can one ask for?

I'm so glad you liked it. The perfect ending involves needing all six character cards as well as the spell. You get a character card for saving a character from a certain predicament.

There's also lots of stuff to discover, such as an unlockable hell mode for finishing hard, alternate costumes for Hiroshi and several cheats (which can be found in a notepad file in the install folder) Also two fun easter eggs are constantly clicking on the bathroom door before you first encounter the Oni as well as an alternate Mika death scene (which is my favorite) in the basement of the Old Building (Save Anna but don't get Mika the compression kit)

I really liked Ao Oni way back then, and it's so cool to see a remake of it!! There's only one problem, and it's that when I start the game and type my character's name, it says "Unable to find file: Graphic/Parallaxes/fog>" and crashes. I tried adding it in manually but it still won't work. I'm using Wine to run this on mac, so maybe that's why, but I couldn't find a fog graphic in the folder anyway. Any ideas?


Okay, it's doing it to me as well., this is odd. Gimme a bit to try and fix it. Thanks for the feedback, I just wish I was informed about this earlier.


I tested the new version and was able to start exploring, so hopefully it's fixed. Thanks for letting me know and don't hesitate to tell me if something else occurs like it.

Hey, it works on my mac now! Just got the Plate Shard and the game looks and plays really good so far, thanks for patching it!
