Really cool game! Played it on browser, to the point it became unplayable (around 22k points).
The art and animations are really good looking, the core gameplay is solid and fun to play, movement is really good, weapons feels good... A solid prototype which screams "Moooore, gimme more!"
My only complaint is that it's a bit on the easy side, spamming turrets is too effective, and the rocket arm, though a really good idea, feels a bit underwelming compared to them...
I join a screenshot where you can see that passed a certain point, power is basically infinite, and so are turrets ^_^'
TLDR : Really liked playing your game, even moving around and playing with the rocket arm is really satisfying, I just would have wished for more with more difficulty! :D
