I can tell you made a really good game here, with a unique twist to the platforming genre and some nice audio-visual flair to back it up. However, I personally just hate these kind of extremely difficult game jam entries; they always seem to lack that certain je-ne-c'est-quoi that makes Super Meat Boy challenging but fair. I think it might be lack of playtime to get accustomed to the game's mechanics that leads to my frustration.
