Knuckleheads

Two noticeably angry metal heads, one purple and one green, swing each other around on a chain through a dark, demonic world. Color-coded platforms, villains and giant fireballs force you to put your heads together properly to pass obstacles and eventually reach the end of the level. The controls can get weird when you’re hanging upside down, but the game is still well worth it.

Planet Runner

In an homage to the best of the worst old arcade games, this is a simple jaunt through a green grid plagued by spiked poles, bouncing circles and large chasms of death. As the planet runner, you will jump, dodge, shoot and maneuver your way through the obstacles, collecting power-ups along the way to help you fend off the evil minions and fight the boss at each world’s end.
