So I see I can make a 4th level when terraforming, but when I've unlocked water editing, will I be able to put water on that level or not? What can go on that level, and can I place a slope up to it? Please and thanks
You can make the 4th level, but you can't climb onto it. The game won't allow you : ( You might be able to make a waterfall if you hit from the side though.
