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.

• Color-mixing puzzle mechanics across multiple stages

• A story revealed piece by piece as you progress
