Good game. Once again, I failed horribly, unless missing more than half of the disks on level three isn't bad?
I agree with others in these comments. Some disks should be like bombs or whatever in other games. They should give you a penalty for shooting them. There could also maybe be different weapons, with different fire rates or at least differing shooting animations. It would make it more of an upgrade game, while still keeping that skill element involved.
Congrats to anyone that took the time out of their day to read this entire thing. Wow to you.
