heck yeah, the game's a lot of fun for me. the art is phenomenal considering this is a jam game and the sound brings it to life .
my only suggestion would be to use the cooling bar instead of health and have the extra work you do reward you with cash at the end of the level (highscore maybe?). that way you are encouraged not to power the cooling thingy and earn money but run the risk of exploding the reactor and annihilating everyone.
that being said, it's still one of my favorite entries so far, good job!
