Took me a few attempts to understand how to play. I love the 2D/3D effect when you spin the camera around, and the controls feel pretty good. I also like how you can upgrade your robots to make them stronger.
I wish the player could have more health instead of dying immediately in one hit, because I found it a little too hard as it is. I also think there should be more sound/visual effects when your robots are shooting at a turret so it's easier to read what's currently happening.
Overall a very cool entry!
