not bad, but a few things you could improve on...
The game is called "Clone" but when you use the power it seems to hurt your chances of winning when it takes your powerups. It makes the player want to just keep the powerups instead of cloning him/her self.
Maybe start the base with a shield?
Perhaps one of the powerups could add another clone ship to your 2?
anyways good stuff, hope to see more of your work. ^,_,^
