I've only played one of the dungeon casually and in terms of runs, but if there's a need for a new category / dungeon runs, feel free to ask for it.

There should be 2 / 3 more dungeons in the game. A 50F and a 99F at the very least.

For people playing on 1.02 with the coordinates and other information displayed, 1.021 patch can be found on this page: http://honya2.sakura.ne.jp/yuuyuutei/html/thhkj.htm

Only replace the files from 1.02 with the ones included in the download

1.021 does not seem to change anything else other than the display issue
