Super Catboy.

Catboy is a fast paced action platformer with a retro 16-bit pixel art look that mixes elements from jump'n'shoot and beat'em up games and will provide an optional co-op mode for local multiplayer. In addition to a lot of varying levels there are plans to integrate several bonus levels in between with an alternative gameplay like car chases in the manner of a side scrolling shoot'em up or riding a skateboard in a urban environment.
