Bad guys aren't the only ones who end up in prison...
Instructions :
Arrows = Move & Jump
Z = Shoot
Escape from prison, one corridor at a time. In each level, one guard will have a key icon over his head. Take him down and swipe his key to unlock the exit, then make your way to the door!
Sometimes you'll need to rotate the room by jumping into the green rotate buttons. This will not affect the guards though! Each guard you kill will drop some ammo; make sure to pick it up. Avoid energy surges, which appear as yellow or red balls. If you die, it's game over!
