Cool thanks. Besides that I don't think there is much wrong with your conversion of the map. You've done a great job.
Though there was one problem, its very rare but every now and then you can get stuck in the rocks in the tunnel when a demo closes it up.
Its funny but annoying at the same time, but its also rare that it happens. If it can't be fixed no worries about it. It does get a good laugh when someone says "Help, I'm stuck in the rocks and I can't get out". heheh
