this is a very clever puzzle game. i quit on level 4 because it was unclear how i was supposed to move the bomb on the 'walk back'. this suggestion is a little late in teh jam but your instructions say 'WASD or Arrow keys to move' but gives no mention or indication on how to 'submit' what step you want to backtrack to, it was only after clicking around and spamming my keys did i realize that in select what steps to backtrack you press S then ENTER to submit. great music btw.
