The idea is to shoot stuff. Time costs you energy, shooting costs you energy. When the energy sphere is on screen, touch and follow the object to get more energy, however doing so will risk you crashing into enemies. Once you crash into an enemy the game is over…
If you fail to shoot an enemy before he goes offscreen, dont worry - he will re-appear on the other side, however this time he will be going faster!
