COLOR BOY

A mysterious monochrome puzzle game that feels like a forgotten Game Boy cartridge from 1992.

You are not matching colors.

You are manipulating energy states.

Every tile exists in one of three states:

DARK · MID · LIGHT

Move blocks around the grid, combine energy states, trigger chain reactions, and transform the board until it matches the target.

ENERGY MIXING

Different energy states interact in different ways:

DARK + LIGHT → MID MID + MID → LIGHT

The full puzzle system is deterministic, so every move matters. Plan ahead, experiment, undo mistakes, and discover the intended solution.

THE IDEA

Each puzzle is a tiny logic problem.

You see the target.

You study the grid.

You make a move.

The energy changes.

A chain reaction begins.

And suddenly the move you made three turns ago matters.

CONTROLS

Arrow Keys — Move Z — A / Confirm X — B / Undo Enter — Start / Pause Shift — Restart

A LOST CARTRIDGE?

COLOR BOY is designed to feel like the kind of small, elegant puzzle game that could have appeared on a monochrome handheld in the early 1990s.

Minimal controls. Simple rules. Surprisingly deep puzzles.

What happens when you combine these two?

That's the game.
