Not actually sure how good this is as a game
The bar bit is nice, normal tycoon type stuff
But like the dungeons? You'd want to automate items, mostly fill it with traps, and have relatively little variety in monsters - because the way it works, you're expected to treat it more like attrition than creating a unique dungeon experience
(Also adventurers take too long to rappel to their death, sometimes they never went down and the item had to be switched, all when dealing with low rarity)
Who knows, good luck with it, just sharing thoughts
