hmm....

this is obviously one of your first games, so i wont be toooooooo hard on u... =]

but..
Firstly... when u wanna rotate that ship (that u control)
make the origin of the sprite in the center, so that it rotates around the middle. (just click the 'center' button on the sprite properties)
the bullets dont come out of your ship. =S
the sounds are annoying...
its hard to control, because of the bad rotating...
not really very original....
