About the game

A glowing blue orb sits in the middle of a painted pond, and two koi, one black and one white, swim circles around it. Ink floats in from the dark. Each koi can wipe out only ink of its own shade, so you have to time your spin to put the right fish in the right spot.

Let the wrong color through and the orb cracks. Enough cracks and it shatters. Levels run on a countdown, and Endless keeps going until you fail, with your survival time ranked on a leaderboard. Shield, Slow, Cleanse and Heal powers open up as you advance.

How to play

On a keyboard, hold Space or ↑ to make the koi circle faster; let go and they glide to a halt.
On a touchscreen, press and hold anywhere to spin, then lift your finger to slow down.
Black koi clears black ink, white koi clears white ink. Mismatched ink cracks the orb.
Levels end when the timer runs out; Endless lasts until the orb breaks.
