@Fifth, I know you are going for the whole ID vibe in your maps but it feels too similar to the original. I know you have done subtle changes, like extra floor detail but I was expected more differences.
@Tronyn, wow nice large epic start entrance, it feels very greek style to me, maybe have the start text in a
greek style font and try 'begin' or 'enter' instead of start? I would prefer to see the screenshot in colour.
