Thanks. I spent a while getting blocks to freeze after sleeping for x amount of time which would have made tall tower building more stable, but with only two days to work on it for the jam after throwing out my original plan, I didn't get it unfreezing properly in time, e.g. if you dropped a block from the top it should be able to knock over the tower from the bottom. So in the end it had to rely on Godot's rigid body physics which isn't really meant for this
