Two levels. Both are pretty intricate, although the first one has some problems on slower machines, due to its extreme size and openness. (It's a huge fortress, and would fit 20 players comfortably.) The readme is (very) misleading about Meo My!... don't give up on escaping the invincibility chamber. Secrets abound... The second level is well designed for KOH or Ball games. (There's a huge lower pool, which would be hard to fight in, except for the fact that all the SPNKRS are down there...)
