Edit: The wad is really called KELLY200 my frontend for doom for dos made the 2 look like a Z, wtf it can be a Zoo for all i care.
This sure doesn't look like any Zoo i've been to and who the hell is Kelly anyway, the person who owns this Zoo needs to know that it sucks
That looks like a beginner's first PWAD which never should have been released. Even Oblige, a random map generator makes better levels than this piece of rubbish.
