I found this thread by search because I had the exact same questions hmpf did. Wow, extremely surrealistic! I'm really impressed by the quality of Morusque/Nurykabe's tilesets! I have simply never been able to figure them out, but I can kind of see how they are used now. Morusque, you have a very unique brain to come up with these.
the way they are ordered in a tileset makes them very confusing and unwieldy to use.
The two black and white sets are, I think, the most interesting and usable in a normal knitt story. And I'm impressed by the water front shot. Very good looking depth there.
Baldwin's screenshots are super cool! I'd love to play that level! Very good use of the not quite Dr. Cliche tileset.
