1 for walls, 2 for background, 3 for boxes, 4 to place blob thing (do this last), 5 for the flag, and space to clear note: collision not added yet, want to make the levels work before collision. pressing 'r' will now reload the level you have erased,
note: if you place two of the same tile on a space you remove the previous tile, but this will not work for making your own levels yet, it will work for playing it temporally but not to save
