I really enjoyed this game. Admittedly I wasn't familiar with the concept of "rock paper scissors" when I started playing so it took me a second to figure out how it worked. Once I did, it was a challenging (but rewarding) game. Agree the death animation was cool and the level design is very intelligent, though I also tended to sprint to the next room if I couldn't figure out a solution. Got a souls-like bleakness from it, for some reason. But in a good way.
I haven't beaten it yet but I feel determined so I will return : ).
