Finished it
Almost totally good >
excellent, with many ideas I've not encountered before, and some pretty room designs. The hold author is a big fan of patterns.
I got stuck on level 1 2W for a few days, mainly because I ran out of patience with the spiral (though the solution was still good) Level 2, 2W, stuck on the last column of this for a long time (excellent wraithwing in a confined space problem) I would have liked a checkpoint within that area somewhere so I could save my progress between the two parts of the last section. Level 2, 1N1E was nasty - I only completed this one by luck, and alot of experimentation.
There are a few 'easy' rooms (e.g. level 1, 2E) and rooms with interesting ideas, but a little tedious in practice, but on the whole, lots of good, and little if any bad.
Level 3, I got 'level complete' but there were no exit stairs. I'm not totally in favour of playing partial levels, since if I want to play the complete level, I'm going to have to go through a number of rooms again. Fortunately, what is in level 3 didn't take me so long to complete so it won't be a big deal (I'd say it's easier than level 2, so far, mainly because I'm much more comfortable with snakes than goblins)
