Thanks, and same to you! The first level of a game jam submission being unplayable is a PTSD moment for me – been there! This time, it's level 4 that's unsolvable, so the other 7 levels are only playable in the Unity Project. Tic Tac Noooo!
I've guiltily added fixed links to the main game page on itch and here. Judge whichever you like. These versions have no other changes besides letting you progress further.
