I really liked this game idea. I only found one key, so I wasn't able to get too far. I would recommend allowing the player to navigate the room with WASD keys. I found the reticle click difficult to use. The reticle should be reserved for clicking interaction points, not navigation.
I thing you have a good thing here though. The room scale was great, and I liked the narration. I hope you continue to add to this. If you do please hit me up, I'd love to play it. :)
I'd love to get your feedback and rating on my game.
