Thank you for the kind words! I agree that the logic for when a black block falls and doesn't is pretty opaque. The rule is that it must have a grounded block next to it to not shake loose. I wont change it to maintain the spirit of the game jam, but I will take your feedback as a lesson for next time to explain mechanics better through gameplay or tutorials. As for gizmo getting stuck on blocks, I'll see what I can do to fix that up, I have a hunch it started happening after some last second change's to gizmo's physics. Thanks for helping gizmo find the treasure :)
