Ummmm, well, I'll start with the good. This concept works well in this environment. blaming is something that your advice should all be familiar with so point for that. There are however quite a few areas that could use improvement such as the lack of a replay button. Also after the game has been lost keeping the space bar down cause shot instances to still be create at 0,0. And a final note is that a shooter of this short gains 50% more excitement if the background is doing anything. 100% more is that background contributes to the game and gives the scene a sense of action and motion.
