Thank you for playing!
Yeah, I took too much time making the battle system and pause menu I don't have enough time to make more enemies. The game does have mimic enemy who appear when you interact with one of the chest, but that monster only have basic attack in this build.
There is an Archeologist inside the dungeon. She talks about the place used to be wildlife preserve and has the required dialogue. She also open a shop. You can found her on the map after getting surrounded by slimes, the same map with the mimic chest. Looking back, I should have put her in more noticeable place.
