i had a lot of issues with this map.
one, it is marked under cube. small mistake, but annoying for me and confusing for n00bs.
two, i couldn't get the cfg to work because most of the textures you've listed are not in dg/ but are in dg_new/
i could fix this by copying the textures over, but that'd lead to bloat that i don't want, and i don't want to mess up other maps which rely on the dg_new/ directory.
so i undid the cfg and took a look. the textures were wrong, so i can't comment on that, but the design as a whole looks great. it just has some really irritating mid-way bugs.
