heh, at some point we doubled the height of the player so the flat wooden structures that were there from before weren't scaled right :P Otherwise it should have been correct.
Building a 3d engine on the Love2d framework is quite a lot of work, yes, and it is what sucked up most of our time. Still, we have a pretty intuitive engine, complete with voxel editor and animation software built in :D So we can use that going forward.
