During the initial placement phase, a coin being dragged over the square gets consumed by the square as well. I recommend having a switch that says “Ready” or “Test” so that square doesn’t start consuming the coins until it’s supposed to go. Unless that is intended effect, then never mind. :)
In level 3, the square eventually moved outside of the view window and I couldn’t dice-roll it back to anywhere close to the coins, so I gave up then.
Keep up the good work. :)
