Damn, this is probably one of the best games of the jam so far. The difficulty is almost prefectly tuned (I has to stop after a while because of a section with 4 guards I couldn't pass), and the slicing mechanic feels sooooo satsfying to use. You feel almost omnipotent with this, and yet the game still manages to be challenging at every level. I also like how you play with the pitch of the music when you die. It must have been a pain to code.
I hope you don't mind if I keep your game on my PC for a while, I need to show it to my friends ;)
