Here's my take - too bad I missed out the (possible) NG area and thus, also missed a great number of baddies (30+). Superb map, by the way.

Nice demos. What I liked most is that when you died, you came back for more.

Yes, by taking the early short-cut you did miss some of the map but as you found out, the map was still playable. I did notice that one of the switchable lights was the wrong way round because of the short-cut but that is easy to put right.

I notice you looked around a lot, was that just secret hunting or scenery watching? If you are up for it, go past the final monster and enter the tunnel backwards... 

it was both secret hunting and scenery watching. As you know better than me, these maps are works of countless hours of labor and love - thus, the most I can (and I must) do as a player is to enjoy them thoroughly. Again, thanks for the great map.

I'll check out the area you'd mentioned. Better than that, I'll replay the map to its full extent.
