So cool. Very much in the style of The Room, and I love the gameplay/settings integration in the record player. I kinda wish the slider puzzle would have kicked me out when it was solved, because I stood there for over a minute going "okay, what now?"
The TV cipher might need a little more scrambling, since some of the encoded words visually resemble their English counterparts and that made the puzzle feel less like deciphering and more like reading a peculiar font.
Good work adding a method to block brute-forcing the final puzzle.
