NetLoller
NetLoller is a variant of NetHack based on 3.6.1. It aims to provide fun and challenge, without too steep of a difficulty curve (I've yet to ascend in vanilla). Also see the original NetHack README in the same directory.
(Originally, I intended on using JNetHack 3.6.0-5, but it proved too hard to make it be aware of UTF-8.)
