Maru is a simple platformer that plays rather similarly to Frozzd, although the tone in both games are practically on different ends of a spectrum. The adventure basically involves leaping from one planet to another to collect the spirits or souls of other creatures that look just like the protagonist, then figuring out how to get to the portal that will transport you to the next area and continue with your mission.

There are only seven stages to visit in total, and most players should be able to complete the entire game in about half an hour or less. (Windows, 12.6MB)
