Mamus

Mamus is a puzzle platformer about making things symmetrical!
This can be rotation or reflection, all that matters is the solid parts of the levels match; if you can touch it, and it changes, it counts.
Mamus boasts 5 short levels showing off the concepts of the game, a customizable background, and 2 music tracks.
