Just found this thread via google, and I happen to have an evil hack I've been making, called Super Not Nice World. There's no custom blocks, sprites, or ExGfx, though I did mess around a bit with the map16.
The level is called "Not nice" and is level 105. It is tested and is possible. Time is 300 seconds, and I just beat it with 15 seconds left.
Enjoy
