It would be great if the snapping mode would make it possible to create walls on a ground-piece and vice versa. Important: Make the regions of the mouse to place something big enough, so that a user can easily choose from placing a ground-piece to the left, a ground-piece to the right, a wall above or a wall below. Also make the snapping possible on both sides of the ground-piece/wall (but that is already implemented I think)
