It's pretty good. It's as user friendly as descript but has all the features for modding. I'll try to post bugs/questions as I find them.

1) What's the difference between steel and flesh on an environment object? If I make two objects steel and make them collide, they don't sound like clashing metal (weapon-clash.wav or weapon-hit.wav) so I don't see the point of choosing between metal/flesh.

Other than that I've only had minor problems (Sometimes I crash if I restart the game while testing a mod)
