Infestor

Infestor is a really nice platformer with beautiful pixel art and rockin' chip music. You take on the role of a amoeba-like biological weapon with the ability to infest and control humans. Your goal is to move from entrance to exit on each level by clever use of infestation of enemies. While in control of a human you can move faster, jump longer, push items and shoot other humans. Once a host has served it's purpose you can release control by exploding your host and move on to the next one.
