Very good submission. Game feels very clean and there are small touches i noticed added into the game like the door having a black fire to indicate its closed. A sound that is played when you enter the room.
I think the one bug i encountered is when you set the volume in the options menu, it stopped the bgm immediately.
The game is definitely lacking more hooks to make the game play more exciting but i believe a smooth clean game > a broken game, or unprogressable game
Good job!
