That's interesting. Well in that case I'd probably win the contest of spending the most time in a level, heh. If I was to play this there's no chance in hell I'm not spending well over an hour on this.
No but seriously, this is a general issue I have with nonlinear shooters, navigating them tends to be a challenge in itself to me due to my heavily underdeveloped sense of direction

. It's even worse if the game features an automap like Doom and the Build games, which I could never learn to put to good use and just looking at it makes me sick... although I admit the textured automap is more bearable.
Out of all the wads I've played, Eternal Doom was the only one where I could actually make sense of it. The fun thing is, that I've actually enjoyed the wad, and would go as far as to say that its cryptic nature is grossly overrated. Yeah MAP30 is indeed a pain thanks to progression being literally hidden behind stuff such as fake walls, but it really isn't as unfun as the reputation preceding it dictates overall. I've seen modern maps that eclipse it in terms of cryptic progression with ease...
