Finally done.
General comments: You have an artists eye, and most of the rooms are pleasent to look at. Please check the spelling on the scrolls, or is it supposed to be that way?
My biggest complint is that the levels are too short. You have a great story line here, fill it in a little more.

×graveyard - clever use of "red herring" - red gate that doesn't need to drop
2000BC - fun with goblins - I love the way the little buzzards line up to be killed.
3426AD - Am I the only one who finds this tile set painful? Maybe add some things to break up the expanse of tiles.
Your house - I hate tar - but the maze in 1E is good, not too easy or hard.
2E - clever use of roaches
3E - agh! those tiles!
4E - this room feels a little trivial - maybe add spiders?
1N - the scroll is confusing
The test - ohh... that mimic/roach maze is evil!
Brain 2 - Entrance and 3S - I'm not fond of sneaky tricks, but they work
The cliff - those tiles again...my eyes, my eyes!
2S - nice use of invisiblilty potion
3S - I did it without the second potion - did you mean for the ability to do this?
4S - maybe put the trapdoor closer to the mother - this gives you a timed room (I can't believe I'm suggesting this)
Brain 3 - 1E is a little tedious. Hack and slash bores me - make me think, instead (which you have done on most of this)
Mini brains - perhaps a checkpoint in the SW corner? this room is a pain to restart.
Baddest brain - others have pointed out the snake room problem
all in all a good hold, not as hard as Dugan's but interesting enough to engage the advanced players. Keep going!
