Love the visuals in this game! Great work :D Encountered the same bug with falling off the map, also encountered another one that I fell through the floor in the tenticle area.
Could not get back to craft potions after visiting the tenticle area - everywhere seemed to need the double jump to progress. But maybe I just missed something, but after dying a bunch to the map and the tenticles I gave up on trying to find the way back with the goodies :). Great job on submitting!
