I was just throwing this out there. but i think it would be better if the foundation/floor of the buildings went under where the walls are so that its more flush and you dont have to build path in the doorways of the homes to remove the grass color. also so that the house isnt built up inside of the walls. another thing i was thinking about was being able to build multi-room structures with walls and doors on the interior. i tried this before on a previous version and the game didnt know what to think of it and could not accomplish the task.
