Pretty neat concept! The platforming is quite decent, and it's a fun short game - I would have preferred to have some sort of reminder of what each form did, but it's a nitpick really - my main criticisms here would be that the player can very easily bypass the game by just running against a wall and jumping, which seems to keep me stuck to the wall, but lets me climb up it, which doesn't feel intentional :p
Other than that, it's a pretty nice entry, especially for a game made under 48 hours, and I had fun playing it to the end!
