About This Game
This game was created as an attempt to gamify the 'Public Key Cryptography Algorithm.'
You wake up in a room filled with cauldrons of colorful paint. By mixing and matching the right colors, you'll solve a series of puzzles — and with each one you complete, a new clue surfaces, slowly pulling back the curtain on a mysterious story.
Who is the girl that appears alongside the butterflies? What does she want from you?
As you clear each puzzle, the game gently shifts from puzzle-solving into a visual novel experience. The ending you reach — the background imagery, the words on the screen — changes depending on the choices and solutions you arrived at along the way.
Key Features
Color-mixing puzzle mechanics across multiple stages
A story revealed piece by piece as you progress
Transitions into a visual novel ending shaped by your results

Reviews
Wow, this game was genuinely interesting and super unique, i loved the artsyle! I also really enjoyed the color-mixing puzzles, they start off simple but gradually tie into unlocking different memories and endings, which is a really clever design choice. It’s a pretty short experience and I’ve only played through two endings so far, yet that alone was enough to leave me thinking about the story. The characters are well-written, especially Hana, who really stood out to me. The ending also caught me off guard, it becomes unexpectedly creepy in a way I didn’t see coming. Without spoiling anything, I’d definitely recommend giving it a try if you enjoy short, visual novel story games.
설명이 조금 불친철한 면이 있지만, 꽤 스토리가 충격적이라 재밌었음.
There are a few strange bugs when matching color buckets that freeze the game, so be prepared for that, but the game is fun. The art is the biggest highlight here, with the story being a close second.

An interesting indie puzzle game with a unique concept of mixing colors inspired by cryptography. The core gameplay is simple and easy to get into, and I like how the story is revealed gradually. The transition into a visual novel with multiple endings is a nice touch, and the music fits the overall mood really well. That said, the puzzle mechanics may feel repetitive over time, and the connection to cryptography isn’t always clear. The pacing between gameplay and story could also be improved. Overall, a short but creative experience with good potential.
