This game's description caught my interest, so I decided to give it a try. My expectations were definitely subverted! By the description, I thought that this was going to be something more like a detective story with less of a focus on combat, but I ended up being okay with a combat-heavy dungeon crawler instead.
I really like the custom spritework you've done; in particular, all the sprites for the major characters and enemies are very nice. I also appreciate the effort that went into constructing all the maps in order to make the city feel more like a living place rather than a linear path back to the dungeon.
There are several issues I have with the balance of the game itself, though. My main issue is that the ability to save anywhere really reduces the risk of exploring the dungeon, as it's not too difficult to just save once or twice per floor and make a run to the bottom on the first day. The treasures in some of the deeper floors are quite strong, too, which encourages such a playstyle. There's also little reason to want to fight the enemies on the deeper floors, as you can always go back to the top in the same day and use the powerful equipment to grind on the weakest enemies. I got up to Level 5 while farming for the demon dust I needed to craft one piece of gear, and at that point, I ended up being very overpowered and defeated the boss in four turns. Almost all of the shops in the city ended up being unnecessary. If you end up revisiting this game after the jam is over, I would love to see the balance of this game tightened up.
Overall, this was still an enjoyable experience! Congratulations on finishing this game and submitting it to the jam!
