Interesting concept! The mirror mechanic is really unique and has a lot of potential. I liked the atmosphere, but I think the gameplay could be clearer. The tutorial was a bit confusing, and sometimes it was hard to understand where to go or what the mirror was trying to show. The camera movement and dark lighting also made some sections harder than they needed to be.
I think with more polish and clearer guidance, this could become a really strong game. Great effort for a 6-day jam, and good luck!
