Bolt

You play as a spaceship which moves across walls. You can swipe up, down, left and right to move in those respective directions. You cannot move while you are not bumped to a wall. Each level is broken up into sections, blocked off by coloured squares. To move past these sections, you must collect all of the coins of the section. There are 30 levels in total. As the levels progress, there are more enemies present, such as moving starships, cannons, laser shooters, and spikes. Those (except for spikes) are eliminated from a section after you collect all of the coins from that stage.
