Nice aeasthetics and atmosphere, music. I think procedurally generated dungeon hinders gameplay for this game. Game doesn't give you a sense of purpose. It throws you into a labyrinth. There's no map or compass. You don't know where you need to go. I saw in the descriptions you wrote that you need to find 4 talismans but still it's tiresome to wander all those same corridors over and over again, not to mention the enemies and collapsing ground which kills you frequently and forces you to start over the game. In your defense, procedurally generated levels are good way to speed up the creation of dungeons but still there needs to be more content in the game.
I think even with all it's flaws and shortcomings, there's definitely a potential in this game. Keep developing it after the jam. Good job and good luck!
