Use mouse-pointer to aim and click to shoot Shoot the enemies before they reach the other side Spacebar to start the game
If 'game over' and 'press fire to start' come up at the same time, press SPACEBAR then the green flag to make it disappear, this might have to be done a couple of times, sorry. If i could change anything about my game, it would be the mistake of myself making the choice of the restarting method which caused an immediate problem. Also, I would've changed the whole game theme since its programming is giving me problems. (filterbot couldn't let me post this to my own comments)
