ah yes guras TRUE size 10/10 for its accuracy


Also I would love to play this on mobile if its possible but it aint nessecary


Is this place actually part of the game? The place looks empty, there's a book there and when you interact with it,  you fight two fog -like creatures using calli's skills. They also drop 0 XP btw.

Will this be receiving any more updates?

morse code:

1- do you acept our gift


Very fun and well written game. Can't wait to see more from you. 

it was really fun and nice, congrats on being recognized by calli

that being said, i didn't fight the secret boss, but i watched a video of it,,, idk what it means,, or i think so, idk,,

also, the credits song is really and nice too


I know I'm a bit late but congrats your game was recognized by DAD and I'm excited to see if you had any plans for the game will you expand the lore and add more characters and will there be a possible android version of the game none the less your game was very fun to watch and I'm excited for what's to come I wish you good health and success and I especially what you to have fun while making it, that's all PEACE!!!


I have some questions after having beaten the game a few times.

1. Can you actually find that mirror in the castle after saying yes to playing hide and seek with it? If so, where is it?

2. I have found 3 books / AO-Chans out on the map. Does collecting them do anything?


Really liked this little game. it was pretty hard to hear any of the music. Crows where annoying, but I was able to to do it deathless, I wish I got to do more fights with Calli, I'd honestly like to see this expanded to a full game. Also an option for the Drip to be swapable would be nice once it's unlocked.

welp, i ran out of ideas so might as well post here, does anyone know what JEFIMIZGH  could mean? asking for a friend.


Its a vigenere cipher, the key is 'red'

JEFIMIZGH means Sacrifice

(2 edits) (+2)

If you open the file called jefimiz.gh that is below the .exe with the notepad and transalate it in a vigenere cipher with the key 'red' will give you this text. 

A.what are you willing to sacrifice for them B.everything A.then what are you waiting for, sitting around wont do you any good. A. let us dance to the sorrows of the humanity you lackthy empress

how do I know what their skills do?

When selecting a skill in the battle menu, you see a description of it at the top of the screen

Don't work on Mac. App just cant be opened

Is there anywhere we can find more detailed information on all things about this game, like a wiki? Great game by the way. Really love the RPG aspect.



I love this game. I wish there is more content

what does the Sanity stat mean?

The San. stat determines that character's defense against other Sanity attacks and how hard that character's San moves hit.

I can't get past the menu screen. I can move the arrow around, but I can't select anything. I've tried pressing enter, clicking, and mashing random keys. Nothing's working.

I'm on mac btw.

Does the key "Z" work for selecting the options?

Is there a way to change to original sprites after getting "DRIP" skins?

At the moment not really.  Maybe I can make it a setting you can toggle after the player gets it.


i keep trying to open it but it wont let me can someone tell me how to open in mac

Hi! I was wondering if there was any way to delete your save file. I seem to be having some trouble getting some event flags to work with the 1.3 update. I actually finished the game in 1.2 (had lots of fun btw!) and I don't know if 1.3 still thinks I'm on my save file from 1.2 or something even when starting a new game. 

Basically, even though I could encounter some of the stuff from the 1.3 update, I couldn't get Gura and Ina's events to trigger at all to the point where I was actually able to sequence break into beating the final boss even though I had only Ame and Kiara in my party. Maybe this could be fixed by deleting your save and starting a new game from the latest version? Let me know! Hope to cover 1.3 in a playthrough with some friends :)

Oh, that's really strange, sorry about that. You can delete the save file by deleting the folder "C:\Users\(your pc user)\AppData\LocalLow\fie\Holo Dungeon".

I'll look into that cross-version bug, because it really shouldn't be affecting a new game.

A follow-up on this. There was a bug that made it so when you return to the title screen from a loaded game, the flags from that ongoing game would persist into a new playthrough. 

That's why the roadblocks from the intersection wouldn't spawn.

Version 1.3.1 addresses that and a Kiara bug at the start of the game.

Thank you! My friends and I were able to finish the game after all. Here's our playthrough if you wanna check it out! :D


I love the game.

It's pretty cool seeing people make fangames of Vtubers like that and with such high-quality on top of that! A very nice job you did here, beautiful art, good music and the story is pretty good, I can't say much about the story as it seems that it was inspired in the events that happened on Ame's first AI Dungeon stream and I didn't watch it, overall, everything was very well made, one thing that I didn't like was how the battle encounters happen, I can't even walk properly sometimes! But it seems that you have fixed in your last update. 

I feel so sad after i finished the game, and after exploring some secrets. there is a bug with the music when entering a fight, and the encounter rate it too high, but otherwise, 9.5/10

(1 edit) (+2)

Fun game!  The scuff system certainly spiced up the gameplay,  and the dialogue was hilarious. 

Bugs (minor spoiler warning!):

  • Rapidly changing areas makes your party disappear (leaving only Ame), at least when you do so between Route 4444 and the castle.  I ended up dying in the battle with the queen and when I reloaded everyone was back.
  • I think something with the Coexist move messed up the states. When I lost Guna, the bleed state persisted on the queen and never disappeared, and Kiame's counter state persisted as well. Refreshing counter adds another counter state. When I revived Guna, I managed to somehow inflict two more bleed states on the queen before she died.
  • In the final battle at least, I used a soggy pizza to revive Guna (is that supposed to be possible?) but didn't update the health bars when anyone was healed. That is, the numbers went up, but the health bar sprites didn't.

Sorry if the bug list is daunting. The rest of the game seemed to run perfectly fine, and again, it was a great experience! Here's to hoping Amelia plays it!

That's actually really helpful, thank you so much! I'll look into it!


Hello! I've really enjoyed the game but I have some questions about parts of the game that confused me. If you'd like to talk, my discord account is Migo#1057.  If you don't have discord, is there any other way to talk to you? My questions contain potential spoilers so I don't feel comfortable talking in this comment section.

you can't see it but theres some dialog that written in morse code (which i haven't decode it yet lol) where the Yes and No has some differences where the No options seems to be longer then the Yes option

Yo I'm a bit confused by the 'secret' ending. There is a blank dialogue box and either yes and no do the same thing. Was it supposed to be 5 fights?


This is an amazing game. I mean all the en hololive vtubers in an rpg? who wouldnt want that! Im a huge fan of rpg games so this is a thumbs up for me. Love the music, art style and gameplay :) Thanks for making such a masterpiece! 10/10 Best game. Best Game!

Yo thank you so much! Had fun watching your playthrough!

What's with the encounter rate being so high? And is tab a quickload instead of another button for the menu (where the load should be instead).

The quickload thing wasn't really suppose to  be a thing, I don't see a use case for normal players, but I use it a lot while debugging, so I left it in. In hindsight tab is a bad key for that, because it's a normally used key, and while testing it out the player could lose some progress.

The encounter rate I really need to fix, yeah.

I just started the game but I really like it, specially the cute art style and the many references!
Gameplay wise, the only thing I don't like that much is that you can't run from battles (or I'm just blind and didn't notice the way to do it)

Whenever I open the game and click the ''play'' button (aka making a new save) my screen just becomes fully purple and nothing happens exactly. I don't know what I can do with this but I'd really want to play this game through start to finish and I'm hoping that you could help me with this 

-best reggards



It looks exactly like this and I do not how to fix it. ^

That's really weird, it should take a second or less before it starts fading into a cutscene. 

Hm, after you click "play" and is doing that transition, do you click any other button?

No I do not. It just happens and I cannot do anything besides it.


I loved it from beggining to end, really really good!

Thanks, I'm glad to hear it!
