I think more movie talk with the patrons and maybe some more choice-based conversation paths would bring a lot more to the game given its environment and the fact that you need to play it through in full without being able to skip much for the different endings.
It’s a solid game but I think it misses the opportunity for a lot more movie geek or even VHS-store related humor, since most conversations don’t add much to the overall story. Technically and visually it’s very sound, though!
