Needs some fixin up
The game really isn't that bad, but then again, it is Space Invaders. The biggest problem for really is the lack of action and sound. It seems like you're really not doing much in the game, like your just sitting there shooting little blue dots our of your ship and that's it.. Also, you'll probably want to go and edit the alignment of the "shooter" and the ship since, as you move to the right side of the screen, the lasers start to fire a good ways away from the actual ship. Other than that, good job, just keep working on it ^_^
