Really cool idea for the game. I like it! Game has great vibe of retro cool game, music works pretty great.
Fight mechanic is pretty great with slow time, for sure it's sell point of the game.
I got some problems with controls but maybe it was related to run out of stamina so I couldn't jump. Probably it's all about platform games where you must polish movement mechanic so game is not too much brutal for player (too hard)
Congratulations on your submission!
