This is an AMAZING game. The art, the music, the sounds and the overall atmosphere is fantastic!
The main mechanic is also very original and can be used In many ways. But the game has sadly one, important issue - it's so hard to the point of being frustrating. I feel like the 2nd and 3rd levels (that's as far as I got) seem like levels 20 and 24 of a 40 level game. This game would benefit greatly from a few easy tutorial levels that teach the mechanic and the nuanced ways player can use it to traverse obstacles. Then, after you are sure the player understands the mechanic and knows how can they use it, you can throw them into the really challenging levels.
