The objective of the game is to stay alive and to destroy as many enemy spacecrafts possible. Also try to collect coins and powerups to help you finish the game. A tip i can give you when playing the game is to just hold the fire button for it to auto fire. Try to avoid colissions and try to master shooting in all directions.. Have fun! Move - arrow keys, Shoot - W, A, S, D keys, Select Space Ship - Enter.
