White CanvaS

Everything is white. Walls, pits and pillars are the same colour as the void, so the only way to see the room is to touch it.

You control two ink-soaked spheres at once: Cyan on the left, Magenta on the right, separated by a pane of glass. Whatever one does, the other mirrors. Bump a wall and it splatters ink across that surface, drawing a map of the room one impact at a time. Because the rooms are mirrored, a bump on one side tells you what is waiting on the other.

Until it doesn't. Every chamber hides one asymmetric flaw (a rogue pillar, a pit that only exists on one side, a brittle block, a portal), and hitting it pulls your two spheres out of sync. Use the symmetrical parts of the room as backstops to line them up again, then roll both into the Twin Exit Rings at the same time.

Your ink is shared and limited. Every splat costs 5%, and a sonar pulse (15%) outlines nearby walls and pit edges. Run dry and the chamber is over.

A short tutorial teaches everything, then four chambers. Stuck? Press H to highlight what can be broken or used. Pick Normal (faint ghost outlines, quick-stopping spheres) or Hard (pure white with borders only, heavier sliding spheres) on the title screen. Your finished runs are saved, so you can chase a better rank.

Controls

• W / S (or arrow keys): roll both spheres forward / back
• A: pull both spheres inward toward the glass
• D: push both spheres outward
• Space: sonar pulse (costs ink)
• H: hint
• R: restart the chamber
• Esc: pause menu (resume, restart, sound, main menu) · M: sound on/off

How the theme fits

Symmetry lets you map two rooms by touching one. Asymmetry is the trap: the one mirrored lie in each chamber. You need both to win.
