A 5-level Nethop, although I'm not sure what happens when 4 of the maps use standard evil physics, and the first one uses a custom model... In any case, these are really well-constructed levels. Fine attention to lighting and sound, and lots of thought to flow. My only real criticism might be the superficial similarities of the various levels (with the exception of Castle Evil)-it might be hard, at first, to figure out exactly which map you're in. The first level was entered into the Evil map competition, all the rest are new levels. A very nice pack.
