The best way to sum this game up is that it's like a labyrinth game but on steroids. Just tilt the device to move your character through the levels while avoiding traps, opening doors, bouncing, sliding and not falling off.
Designed by game industry veteran, Anders Hejdenberg. Lead designer of many world class games, including Battlefield 2: Modern Combat.
Episode one is roughly an hour long with ten action-packed levels that will have you bouncing, sliding, spinning and swerving all the way to the finish line.
Put your skills to the test by completing the game with gold star results on all levels and prove that you are the true master of Dark Nebula!
