Saving & Loading now works. It now uses tile names instead of numbers. @Maple_Studios: RED ALERT. Inside of the project you will find a My Block with 8 empty boolean inputs. Fill these in with the following: 1) Returns true when the tile above the indexed tile is empty. 2) Returns true when the tile below the indexed tile is empty. 3) Returns true when the tile to the left of the indexed tile is empty. 4) Returns true when the tile to the right of the indexed tile is empty. 5) Returns true when the tile to the top right of the indexed tile is empty. 6) Returns true when the tile to the top left of the indexed tile is empty. 7) Returns true when the tile to the bottom left of the indexed tile is empty. 8) Returns true when the tile to the bottom right the indexed tile is empty. Then remix and share the project.
