Maybe you should have like these drone thingies that follow you around and attack your enemies, and you can get more than one, also you should be able to get different kinds of them like ones that defend you and others that heal you, and maybe you should have some sort of spell thing like calling down a missile storm.Another thing is that you should have to upgrade your eyes to make your lasers stronger not upgrading the head. And maybe your should add some sort of story behind the whole thing with a free play. And maybe some sort of multiplayer, and definately a boss level or a couple, with a variety of enemies.
Doll: That's a weird place to out a garbage can.

Me: No, the ceiling's an EXCELLENT place to put a garbage can!
You could make a special unit for each team! For the computers it spawns every minute or so, and for chaos...... you have to unlock it. Or you could choose your team!
I already have one special unit in plans, the Chaos Lord. I don't think you will be able to control him though, unless I find some way to make it possible. You will only be able to spawn one and his powers will be increased as you put more skill points on him.
