A true classic. Loved this entry a lot. The style was great, combat was straightforward, the dungeon crawling was enjoyable. I particularly enjoyed the level with the invisible monsters that you would kill by sound, very nice touch.
I didn't get to the end because the game crashed for me at one point during the level with the invisible monsters so that was a bit sad. The only confusing thing was the fact that the floor/ceiling moved even when you moved in an invalid direction which was a bit strange sometimes.
All in all, fantastic work, very detailed, very enjoyable!
