I had so much fun playing this one. Not a single bad level. Out of the official releases, i think this is the only wad that can actually compete with Plutonia in terms of gameplay and map design. As for the difficulty, is a really fair challenge, a little easier than Plutonia but still a formidable challenge. Also, i love the fact that is only 9 levels. The 32 level standard for most of the famous wads is a little too much for me, honestly.
