technically not my first wad, but the first that i have completed. its pretty short. so dont expect too much. and there are different enemies/items/all that depending on the difficulty. though it was designed for HMP. i haven't beaten on nightmare so try that :) i'd also very, very much appreciate feedback, thanks!
ive only tested this map in GZdoom, so use that
In the Doom 2 format
No Jumping/crouching/freelook (though freelook wouldn't completely break the wad, i wouldn't recommend it)
