How do I beat B4? There's no way to get the lower blocks up because there's always at least one rune blocking the 2X2-sized mouse wheel, the ceiling blocks can't be moved at all for the same reason, and the player can't jump high enough to reach the gold/goal from where the blocks are. What else can I do? The mouse wheel can't be shrunk to move the blocks between the runes, and none of the tiles can be moved out of bounds from the building, either. What am I missing?
EDIT: Oh, never mind, you just chose to introduce the thin wood planks in a very unintuitive way, making them look like part of the unmovable tile.
