I can see it's been a while since I've posted an update, so this is just to say I'm still working on it, I'm almost finished with the last few chambers on the first map and planning to make my own maps to add to the story.
I've found someone who can help with the pathing and modeling for my map, which might help it look a bit better and more playable, Still looking for a programmer who can help me with the portals and other fine details.
If all fails I might just have to learn a few new skills and do it myself, might take a bit longer but I'm willing to put in the effort for the time being.
Take your time, every mod needs time and as your the only person remaking narbacular drop in source I think you should take your time. And hey even if you don't manage to do it, atleast you learned something new.
