These might be rubbish but they're all I've got...
-Balloon popping game
I was thinking of a balloon pop game but theres to many of them, I will take your ideas into consideration, Thanks!
Hmmm... How about a dodger game? The enemies A.I. Would be programmed to, once within a certain distance, lock on to the players current location, and then take a dive for it. If it hits the edge, or certain obstacles, instead of the player(that's where the dodging comes in), then it is destroyed. You could have some simple power ups aswell.
