Ok, I played around with WinterMute for a couple of hours. While it seems like
an interesting 2.5D engine, the documentation is just to poor to really getting started
with it. To make things worse, the few games I looked at and that are using this engine
didn't work all that well. If you need ctrl-alt-del to exit a game, that's bad..

I think I'll stick with GS to develope my game for now. I'm sure that I can figure out how to
make a good looking 2.5D game with it.
What does it take? Slapping a pre-rendered 2D image on a ground plane and have
a 3D character move around on it, aided by hidden geometry? That can't be that hard!

Or is it..
