A number of bugs have been reported in the version I uploaded. Some of them make sense and will be fixed by the new save/load system, while others are entirely insane. (Spawning in terrain? That shouldn’t be even remotely possible.) I’m wondering whether some of them aren’t simply due to Windows Vista – if so, there’s probably nothing I can do about those.
Anyway, I have to go to work soon, but I’ll have a (relaxed) look at these issues later today. I think we can expect version 0.9 to be released in a few days; if, that is, I can make a version that most people will be able to play. We’ll see.
