Chemichaos!

You only need a mouse to play.
Hold left click to push away the chemiballs but be careful, they're very bouncy!

As you'll notice, the primary coloured chemiballs can react to form secondary colours.

The grey chemiball is inert with everything except another grey, in which case it will produce an explosion that'll knock nearby chemiballs around.
