I'm making a game with a sort of unique approach to it (although it sadly is like Pokemon Island, if you played that). This is where the wild pokemon would be and a few trainers, much like a route in official games. I don't know if I should have a closed off area like on the left with stairs to get to the next floor, either up or down, or if I should have them all connected together on one giant floor (it would have more than one connecting pathway like shown, I just wanted a visual example).
