I'm used to play Tibia, a 2d oblique projection pixel art game. It uses a multiple floor system (15 in total) that adds "height" to the map.
Levels go from 15 to 1, 15 being the bottom height and 1 is the floor at the top of them.
Under level 7 is underground, but above this level you can see all the upper levels.
Is Godot capable of handle a map like that in a 2d game?
