That’s the tricky part for sure, but it seems very doable. It wouldn’t work as well if there are large height differences between the tiles, as the sphere collision will be perfectly smooth, and the player could end up clicking through hills and hit the tile behind. For relatively smooth globes it would probably work well, though. I’d love to try to help you find out how to reverse the projection math, but I have to spend my free time making my turn based system marketplace ready. I’ll chime in if I think of something clever, though
