Yeah, I like how you've built it that you kind of get to know a bunch of the adventurers, it's a really cool way to add some character to them. Also the mimic is a peak character I wish her her best life and can't wait to see her full sprite.
Also, I just remembered, there was a part where the skeleton was like "maybe you should let some adventurers through, they might find cursed items to help you out" which seemed like an interesting mechanic to almost build rapport with some adventurers or a mechanic based on trust and suspicion that never really seemed to go anywhere.
