I didn't find it entertaining. It just felt like wandering around hallways. I found the door not showing up until I light it irritating, but I don't think it's a bad design choice. I think it needs a new element to add some excitement. If there was something chasing me, or I was collecting something I would find it interesting instead of irritating. I also think a smaller level would have been preferable, and if you do make more, gradually make them bigger. It felt like being dropped into an ocean. Overall seems like a solid foundation but needs some spice.
