I'm really sorry for you mate, I had the same nightmare scenario at a jam, you must feel really bitter. Still tested your game nonetheless, and really it's too bad it wasn't functioning at deadline because it was a good puzzle game ! Stopped playing 3 levels into the shovel because it's late.
I hope you'll manage to put this bad experience behind you by creating other games in other jams!
PS : And thanks for reporting the bug on my game
