Use the arrow keys to move, space bar to shoot lightning bolts. Try to shoot the space hippos (worth 1 point each). Avoid the oranges and the hippos! Health packs will randomly spawn giving you extra lives. You lose the game if you lose all lives. The aim of the game is to try and get as many points as possible.
