Pretty Nice Game, i couldn't beat it even after 6 runs unbeatable at portions sadly, you can't jump high enough if you miss certain keys, I reached the purple chest for example and nothing really happened besides the screen shaking, the chest wouldn't even open. overall it's almost there, I'd make another update if I were you, get all the bugs out of the way and make it possible to backtrack.
very nice project besides that, I really enjoyed the cutscene, art, and overall design.
if possible, I'd love it if you could check out our game as well :)
