Congratulations on making your first original game! :)
I like the atmosphere of the game. Definitely has some potential!
I think the maze-gameplay needs some work to keep the player engaged. Reaching a dead end and having to backtrack feels a bit punishing, IMO. Maybe if the dead-ends had some sort of reward, like getting a text-prompt, or discovering some interesting lore, like a poster or some furniture? Hope it helps :)
