oh, wonderful presentation! and this type of "complete the level" platformer with a climbing twist is a good idea.
unfortunately i made the mistake of trying the hardest difficulty first, confident in my abilities... and there being no way to reset the game state without sitting through the piece settling (sometimes they wobble for a really long time) and then jumping in a pit, actually hurt my patience a lot.
it's just missing a reset button! if it turns out i missed one i'll come back to this asap
