what "broken" means?
It means it doesnt work. As well as other things, You cannot free any created Entities, so in small demos it looks good, but in anything that needs you to delete entities ie change level, you run out of memory.Skid has said this has been fixed, but hasnt released the fix yet.
Basicly, if you look at the Bug reports, (If you can if you havent bought it), all those bugs are still current, because even though most of them have been reported as fixed, no fixes have been released
