Just got around to trying this out and beat all the levels and got all the little skins. Amazing concept, the sinister art design is really unique in a platformer. My only critique so far is that the spinning blades are the only obsticale. My recomendation would be to add a level where the player is chained up similarly to the skins that can be found and the player has to swing onto one of the spinning blades to free themselves and land safely.
