Also, the Imp Dungeon frequently softlocks. The game randomly selects rooms to use, except one of the rooms (with multiple doors to try to pry open) is broken and none of the doors open to proceed further. If the RNG picks this room, there's no way to progress, and you have to quit the dungeon run.
You're not out too much resources for it, since it's just a rope, but- It should be an easy fix to just remove this room from the dungeon pool, anyway.
