Balls to the Walls

Guide the balls to the walls in this simple but challenging puzzle game. Use arrow keys or WASD to bring each ball to the wall of the same color.

This was my first game, originally made in 2015. I've finally got around to porting it to WebGL so it's playable again. I've tried to retest it thoroughly, but Unity's APIs have changed significantly since then. Please reply if you find any bugs!
