So you did break the B22 curse Oscar! My best formal run is "Got AofN but Killed by Troll at B19F". I was so, so Trolled. I find using Wand of Confusion / Hypnotize Mon to make a monster block the hallway (and thus other monsters) helps a lot. And don't be too afraid to use the accursed Ring of Teleportation. Japanese creator Neko800 made this game and yours truly translated it.
