Okay, the game concept is great, and hand drawn graphics just elevate the experience. The music is awesome too!!
But you REALLY gotta put some extra time on UI/UX of the game. Add affordances, like interactable object glows when mouse is hovered over them, or (and I STRONGLY recommend this) a pulsing arrow on either side of the screen to indicate play can go around the room.
There is a great conclusion to this game, I can feel it. I just cannot reach it yet.
