I'm not sure if anyone saw it because I posted it so late, but here some screenshots from my first map, an E1M1 remake. I'm so close to releasing it now. Maybe this week!
It's not one of those 1:1 interpretations of E1M1. It was more like trying to take every element of the original map and turning it into something functional. The result is a map that echoes E1M1 but doesn't explicitly reference it.
