Really cool idea! For me i whould like to see it being harder - most positions in "rooms" are reachable from just jump so teleporting with physics have no real use. Anyway well done!
Thanks for the review :). My original setup for the boxes was indeed harder, but since it was from a jam, I didn't want to scare people hehe. Also, I played with the spawn time (and bomb timer) of all three items in the game, that decreases with the score, maybe they should decrease faster.
