I'm currently working on a new 32x32 tileset for Nethack. Why? Well, I think Nethack is a so great game that it deserves more polished graphics (with all the respect to the developers). I also feel that many people don't be interested in the game because of it's appearance. I am trying to make good-looking tiles while still being coherent to Nethack's universe. I made 68 tiles until now. The total number for a complete Nethack tileset is 1057 tiles so, it's still on the very beginning and there's a long, very long road to go. But I hope to finish it as soon as possible.
