Nice little game! As others have said, larger explosion radius would be nice. Sometimes I'd see a few go flying, but when I hit one dead on, even if he's surrounded by others it seemed like just the one I hit would die. Other than that the controls were smooth and the shooting satisfying. I like having the health bar on the back of the mech. Always fun to try and put as many things that would be UI elements into the game itself, much more immersive. Agent AI could be a bit more interesting, but with the time you had this is fine. Good work!
