You've got a good game possibility, but you've also got a lot of problems.
1. I really could have done without being insulted so much throughout the game.
2. Holding the mouse button down to charge your shots doesn't make your shot more powerful, or anything else for that matter.
3. The enemies move way too fast for you to be able to dodge them, and they always zero in on you. Once on top of you, you cannot hit them.
