There might be very slight/small invisible walls. but I've probably played about 2 hours through all the tests in this map in total. Theres no hindering bugs afaik. Also I just couldn't be assed to lightmap it anymore, theres like a time where you have big visions for your map and you really want to make the best of it, well thats over for at least a year in this map
. Anyhow if you want you could lightmap it, but it wasn't mapped really well (my first map, sloppy). Besides, it has a fake lightmap so it should work on fgunz. if you're up for it though, be my guest.
