A downloadable game for Windows, macOS, and Linux

"You're not prepared to deal with the truth...are you?"

A mysterious golden letter is sent to a select number of people... Its contents are unknown.

Project Kat is a short, unconventional RPG horror game in which there is always another way. Solve puzzles, make friends (or not), and guide Kat as she attempts to uncover the mystery behind a strange golden letter.

This is a story-based puzzle game where each puzzle has multiple solutions and outcomes! There is always another way.
The game is playable in about 45 minutes and contains multiple endings depending on your actions.

This is the prologue to Paper Lily, the full game (currently in development), but it's also a standalone story that can be enjoyed on its own.


May contain flashing lights, some blood and unsettling scenes. Proceed at your own risk. 
Just kidding it's really not that bad. But still it's a horror game :) 


We are 2 idiots making this game in our free time and this is our first project of this size! We would love you for eternity if you could leave us a comment here or a review on Steam!!!

in my opinion this game was good and fun! It has some similarity with corpse party the game and i love the artwork aswell it was excellent.
and my advice is to add more characters to the game so that the game doesnt feel boring by just focusing on one perspective and make them playable just like corpse party so that i can get emotional with them when something happened to them.
Aside from that overall this game had a good start and i hope this game will be a "corpse party like game" due to how much i love a japanese horror rpg with school and mystery themed anyway good luck Leef.  :)                                 

this was really fun, interesting story, creepy atmosphere, like the change in play style inbetween the game, i unfortunately got the bad ending, but nonetheless it was really fun keep up the great work!

AHH LOVED IT! Even if I'm a bit useless in games i managed to finish this one pretty easily lol. The whole theme is great and in my opinion the jumpscares were as spooky as needed. I'm super excited for the rest to come out!!

its august 2022 now...

Super cool looking game! i definitely enjoyed the art and characters included and would love to go back into it to try and get some other endings. The gameplay was also very fun, and i love the concept of the choices not always being what they seem even if i did struggle with it a little bit. Despite that, a beautiful game! Definitely gonna keep my eye on this one.


I am very excited for the full game, i really like the protag shes so cool!

I hope you wont give up on this game! :)


Very impressive, can't wait for the final game!


hey there, Leaf 6010! just found this guy https://gamejolt.com/games/projectkat/742479 reposting your game to gamejolt - did you give him permission to do so?


I hope to god this doesn't turn out to be another dead project.


Not likely so far :)

I have been waiting for a while for the full game to release, I am very very excited for when it does come out :D

tried downloading it on mac but it said that the 'file was damaged'. anyone know how to fix this?? :((


Hi there! Please read the section "Install Instructions" in this same page ^^

Thanks! I figured it out.

Does anyone know what the "C" key is for? In the "readme" file says that it's for something "special"...?


Hi there! The C key is used for certain situations that may need an extra key (for example, to reset during the desk-pushing minigame).

Don't worry, there is no secret place where you can use it (yet)!

Ok, thank you very much!


Would love an android port


Try joiplay my friend

Did you try to play it with joiplay?

Did it work?


yes it worked

how? I tried to play it with joiplay but It didn't work 

Only black screen:(

This was such a fun play! I really suggest that anyone who plays this takes the time to explore their options, since there are a lot of things that they could've missed on their first run :} 

bro its july now


be patient its kinda hard to do these type of game not trying to be rude

Originally planned to play it in multiple sittings, but the game dragged me in too much and ended up finishing it all at once. 

Really well written characters, could easily feel their distinct personalities. Everything is very cute until it is not.

the pixel art is very cute! cant wait for the full chapter

Really enjoyed this! The story's short but very immersive, and really hints at what might yet come - I'm looking forward to Chapter 1!

Also, it was really satisfying finding some of the different endings and different ways to play through - just simple changes, but they really altered the tone of it, which I appreciated

really neat game, really want a chapter 1 now

looking forward to chapter 1. This was a great game.

Very nice game! :D

This game was amazing! I'm looking foward to see chapter one, I see a great potential in it! Loved the game so far, the art and gameplay were amazing, I wish you an amazing work in making the rest of the game! I'll surely play chapter one when it comes out.

this was wonderful

This game was mindblowing!! i freaking love the mysteries and the art ( i love horror cute pixel games) i managed to pull 6 endings but the last two i got too lazy for so i kinda just looked 'em up. But awesome game!! i loved this!!

I just played this game and I'm really into it! I'll be keeping a close eye on updates, and I hope it comes out soon. Devs, I think you have something really special here!

The game is cool, i only manage to pull 2 ending.

This game is a SuS


i just finished the game its amazing >w< , I really like the mechanics of the game and the kawaii character design, the dialogs are also hilarious but spooky, at the same time. this is easily one of the best horror games ive played through this year!! i'll be rlly looking foward to the release of chapter 1, theres so many mysteries unsolved.....                                                                           anyway keep up the good work!! (*^-^*)

WOW AMAZING!!! id love to play the full game once it comes out. i am very curious on who she is looking for and why she is trying all of these rituals to find them. 

Es un juego magnifíco.

Con gráficas hermosas, una jugabilidad sencilla y una pequeña prueba de la historia, que de seguro una vez completa será una aventura inolvidable.

Entre más juego, más me enamoro. Aunque esta "crítica" sea más bien una alabanza, no tengo más palabras para describir la buena calidad de este.

это хентай???

срочно ответ нужно!

Нит это хорор

блин :((((((((((

блин :((((((((((

This game is really good, the plot twists is absolutely amazing but the storyline is somewhat boring and interesting at the same time, I really do recommend playing this game if you're a fan of Horror RPG games. and the creator itself is a very creative person (well, at least that's what I think LMAO).

First episode.

This is literally the best RPG indie i play in a while ... i really hope to play this game when its comes out  10/10 keep up the good work 

i wanna play paper lily where can i find it
