This is so awesome, missile command is one of my favorite arcade games!
Everything was executed so well and there's lots of polish throughout the entire game. I'm impressed.
I'm 50/50 on whether I really like the controls or think they should change. It can be frustrating when you're trying desperately to get your cursor across the screen to zap somebody, but that limitation is part of the challenge.
Using the mouse to aim would make it less frustrating, but if aiming becomes that effortless, you'd probably have to rebalance the whole game!
