Pity it hasn't been updated meaningfully for over a decade - perhaps it just hit perfection?
Though I've ascended a few characters, I haven't tried to do so in a while, mainly because of that long, slow slog through the mazes. I'd consider changing things around so that there's maybe a 1/10 chance of getting a maze on any standard Gehennom level - or better yet, only the special levels get mazes.
Funny how the wizard is one of the weakest characters at the beginning of the game, but becomes almost unstoppable at experience level 30. Reverse-genociding purple worms, taming them, and teleporting them away can really be helpful on the Astral Plane - a bunch of pet purple worms can really wreak havoc. Even one pet purple worm can be handy in Minetown (though I take care to lock Izchak in his shop when I clean out Minetown).
