The overall concept of this is a lot of fun and I really like that you can consume the beads (if you must). All the enemies are really good, especially the Bell-Sworn.
My only critique is very much personal preference - but I'd like to see less random generation and more specific choices made about where beads, enemies, traps et c. are - so that they make sense in their locations. This goes more for the traps than the enemies, it's harder to see why e.g. a bureau would be in a staircase, whereas it makes sense that the enemies are moving about.
