I really enjoyed this. Short but sweet. The soundtrack and lighting really played well together, felt like a cool retro grungy vibe.
Gameplay was a bit confusing at first, but reading through the comments here I got it, and found it really fun.
My only recommendations would be minor stuff that obviously it’s hard to get to in a jam, like making it a bit more obvious when you’re taking damage. That, and well, I’d have liked to be a bit longer, which I think is a compliment, really.
