I've tried to analyse the behaviour, but I couldn't find any conformity  
(in Oxyd Magnum). It seems that Oxyd selects randomly one free position  
near the spawn-point. The Oxyd behaviour is far from perfect. It's  
possible to spawn around stones you cannot push away, so you are trapped.  
I tried Magnum #59 "Work or Think!" (the level Jacob mentioned), and in  
this level it's even possible to respawn in a part of the level you  
normally can't reach (I attached a screenshot). If I try to leave the  
level at the lower side, Oxyd crashes.

Sounds great. :)
