Substance is a puzzle retro-style game where you fuse chemicals together to make new chemicals in order to complete a level. It features a level editor, so that you can create puzzles for yourself, other people or just to add to your big puzzle library.

Substance also uses Greek letters to reference each of the different chemicals. That's... good!
