My running project uses 2d isometric world (employing Isometric Grid extensions). I consider buying FIrefly and reworking the game to be in 3D, well rather an experiment, but my main concerns are:
1) Can Firefly world coordinates be somehow tied to isometric grid coordinates? I doubt it as that is based on 2D coordinates on the frame, so I would assume that rotating would not be possible.
2)What is world size limit?
