I'd love to see a clip or explanation :) I thought I made it pretty cheese-proof but if you found a way then congrats! The intended solution is in the walkthrough video linked on the page (the embed is broken due to godot funkiness).
I would have liked to have an undo, like in Baba Is You, but I couldn't figure out how to implement it with the code structured the way it was. Might try it later, though.
