I think I'll try my hand at this, albeit my skillz are fairly rusty... @fai1025 Seeing that suspicious gap, I'll go ahead and take MAP18.
And due to that placement, I'd like to inquire with @StarSpun5000 and @SharkyChip as well, the map prior and after respectively: what do you say to organizing things a little? I'll admit I enjoy that idea of mini-episode breaks suggested earlier, but since thematic correlation doesn't appear intended it wouldn't hurt to consider gameplay factors to smooth things over in continuous play - how intense things are in difficulty and monster count, primary weapons and demon types, etc?
Anyway, hope things go smoothly! We can probably have that be a quiet exchange in PMs to help keep this thread clean.
