"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!!!

Thank you!!

This game was incredible for a little pixel horror feature! I loved it, it was very spooky and well made! I especially love the artstyle and the music! Great work!

well, I just played and to be honest sensational, a very well crafted art as well as every detail, a good game, gave me goosebumps, thanks for the beautiful work.


Pretty cool, however, near the end when there's book Lily can't read. It gives me a weird vibe she's like, somewhat illiterate. Probably not, but the vibe is to strong for me to continue playing any of the other games

I can`t get enough of that game! It`s so cool, like eating and sleeping at the same time. But also it is difficult to play,it is so nice like the chinese tea to a yummy scone.



Very good game with a very good quality in drawing by hand and arts. Story is nice and multiple options in puzzles give to content a long life.

i'm on MacOS and it says the game is damaged and can't be opened ):

This was definitely amazing! I have so many questions about the three other girls and what happened to them. The true ending was so creepy and I wish we could know more about Kat and who the guy she was trying to find!

If anyone's interested watching me play the true ending and starting out the main game "Paper Lily", here's a video!

Would definitely recommend this to those who like RPG horror games :))

Definately worth the time.The art is great!

God man this is sooo good, time since last time i played an rpg like this, even if it's a prologue, it's short but good enough

2nd video!


I like the vibe, but can't fully understand main character's motivation and the plot itself by now. So I am curious to know more about it! Thanks for the game, waiting for the full release :)

This was so much fun! I really love RPG Horror games and this was great! I streamed playing the game and I didn't get the good ending tho, only the bad endings HAHAHA. Still fun tho <333

sooo good! i love rpg games like this. the ending is unexpectable though, but i love everything about this game <3

Hi! I didn't finish playing yet but here's the part 1 

ok but now seriusly  can someone please tell were does this connect to paper lily

(1 edit) (+1)

So, you see, Za Wardo is the ultimate stand

OK like I love the game but like when does this conect to paper lily's story?


My name is Yoshikage Kira. I’m 33 years old. My house is in the northeast section of Morioh, where all the villas are, and I am not married. I work as an employee for the Kame Yu department stores, and I get home every day by 8 PM at the latest. I don’t smoke, but I occasionally drink. I’m in bed by 11 PM, and make sure I get eight hours of sleep, no matter what. After having a glass of warm milk and doing about twenty minutes of stretches before going to bed, I usually have no problems sleeping until morning. Just like a baby, I wake up without any fatigue or stress in the morning.

I was told there were no issues at my last check-up. I’m trying to explain that I’m a person who wishes to live a very quiet life. I take care not to trouble myself with any enemies, like winning and losing, that would cause me to lose sleep at night. That is how I deal with society, and I know that is what brings me happiness. Although, if I were to fight I wouldn’t lose to anyone.

[Modified English variant] – You can call me Yoshikage Kira. I’m currently 33 years old. Not that you’d care, but I reside in northeast Morioh’s villa district. Also, I’ve yet to marry. In order to make a living, I work for Kame Yu department stores. After a long day’s work, I return home no later than 8 PM. I don’t like smoking, but do enjoy the occasional drink. I’m always in bed by 11 PM, and I make it a point to get no less than 8 hours of sleep each night. Before bed, I drink a warm glass of milk. It’s always coupled with 20 minutes of stretching to decompress from the long workday. Sweet dreams are the usual result of this.

I then awake as refreshed and recharged as a newborn child, ready to take on the day’s challenges. And after my last checkup, I was given a clean bill of health. For as long as I could remember, I’ve done everything in my power to live a productive life that allows me to pursue a lasting inner peace. This may be a foreign concept, but I choose not to concern myself with winning or losing, life’s troubles, or enemies who bring sleepless nights. That is how I cope with this backwards life we find ourselves living. It’s what brings me happiness in a world fraught with hardship and misery. Of course, if I were ever to engage in combat, I would win the battle without question.

okok that makes sense thank you

It was fun to play and explore, but I hate the ending. I'm not a fan of that kind of horror.

Definately 10/10. This is second best 2D game after Corpse Party. I hope this game became popular so the dev in next chapter will hire a Voice Actor to voiceover the girl especially my waifu KAT <3

the door is so creepy


I just noticed that the tags mention RPG Maker, albeit the game is clearly written in Godot, judging from the project's file structure.

Great character designs, btw.

I recorded my play-through, was definitely a great time and I cannot wait to play Paper Lily!

The perfect game to get obsessed about cant wait to play paper lily <3

Perfect, the art ... the music .... intractable objects made the game feel alive.

in general loved it <3

thanks for making it free to play :)

what tile is used, very perfect


This game is amazing!!!! I loved it when i played  it the first time it came out. One question, the game is not completely complete right?

recently, the main game, paper lily chapter 1 was released.

Where can I find the Kickstarter link? Tried looking for Project Kat directly and couldn't find it... strange

nvm! https://www.kickstarter.com/projects/leef6010/paper-lily/

I am BEYOND EXCITED!!!!!! Dowloading <3 <3 <3 Thank you so much (ɔ◔‿◔)ɔ ♥


i love this game! it really reminds me of omori! im exited for more of this game to come out!


This game was amazing , i speedrun to the true end , but i played for all the other endings off cam, and IT"S EPICCC, Currently editing the Chapter 1 playthrough , will upload soon on ma chanel

This game is soooo amazing and interesting plus the art is very beautiful I'm very happy that I found this masterpiece :)) Still amazed that it's only a prologue so I'm looking foward to play the main game. On my way to talk about it to my friends

hello, im on mac and when i opened it the game says that "its damaged" and theres no option to open it at all. if anybody know how to deal with this please tell me ^__^ ! i was so exited to play it haha

Excuse but may I please ask if it is okay

"What RPG maker did you use in this?"

Also I love your game cuz it's so amazing and so kawaii~!
Love the art style and Kat reminds of Nezuko having short hair!


Thank you! We're happy you like it!

It's actually not RPGMaker, we used Godot Engine to make Project Kat ^^

Thank u 

( ^^)


wait can anyone answer this if i download the game will it like crash my pc bcuz windows keeps saying "this isnt same" and other stuff


i played this game 2 years ago and it didnt crash my pc its a rpg maker horror game

okay tysm  


How many endings dose this game have



no, the game has 8 endings


i only knew about 7


you can see the 8th ending wasn't so obvious to you, you can still make that ending, I'll just say that while running through the whole hallway after using the door key


One of the best horror games ever. The game play is high-quality, the dialogue is thoughtful, and the world is immersive! The art and graphics are really, really good too. But, if I had to pick a favourite, I would say the horror. It's not an over-the-top total gore fest with nothing but gore, but also not boring clichés of supernatural events. It definitely has supernatural themes, blood and gore, and is generally disturbing (in the best way), but it's very tasteful and well-used. I can't wait to recommend this to my family and friends, get as many endings as possible and let it overtake my life.
