I really liked your use of color saturation for health level, I thought that was pretty cool, especially with all the colors from the orb projectiles and I think the transition to the new unit upon death was pretty good. I think it would be fun if there were some movement abilities like a dash or something, but I also get it's not necessarily that kind of game. It was fun jumping around, dodging projectiles, and picking a new gun to get killed by so that I can use it. The scaling of new projectiles types and weapon types was pretty good, maybe a little faster? Fun game overall!
