This game’s 67 levels are divided up into 4 zones. Each level starts off with a limited number of electric beams and 3 hop/push charges (unlimited after v 1.0.5 update!) that you use to find your way to the exit. Each level also has a time challenge, which breaking will give an A rating. Obtain an A rating in all levels within a zone to unlock the 16-bit extra level.

Additionally, some levels have a plus (+) object collectable. In the top right-corner of the zone map it will indicate how many there are left to collect. Get them all to unlock a new battery skin, selectable from the main menu.
