Well, the blitting engine I’m using uses tiny Bitmap Sprites that represent some bitmap. Those bitmap sprites are all drawn to the same bitmap (map) so yeah, you could use isometric too I supposed.

btw, blitting cannot be used for isometric maps rite? I don’t see how it can be as efficient anymore with depth sorting… At the very most, i suppose each level can be blitted, but anything that is not flat/floor has to be in its own separate layer as a sprite, and that includes walls/buildings.
