The goal in the game is to infect all yellow shapes with brown color by colliding them with brown shapes but keep all green shapes uninfected.
Press B to toggle Color Blind Mode. Press 1-9 to set game speed. Default is 1. (I strongly recommend you set it as default when you play the game first time.)
Updates- 2009.01.04 add color blind mode. Press B to toggle it. (balls embedding a square are brown balls, balls embedding a triangle are yellow balls, balls embedding a Y are green balls. Squares embedding a + are pink destroyable objects)
