Wowow, thanks so much for sharing!
I'm so glad you were able to catch so many of the connections between the different nested worlds/dimensions, including the sound system (that ones more of an unobvious one). I see what you mean about the different (happy) ending; I think we just wanted to focus on the big punchline which is to somehow make the real player (you) feel as uncomfortable as possible; y'know, the whole make you feel like "you're next" thing by keeping it as immersive as possible with repetitive reinforcement/association across the dimensions. Glad to hear you liked the chat! And thanks for the suggestion on the short horror story compilation!
And an absolutely huge thanks for sharing this! We would love for them to try it out and let us know their experiences.
Cheers!
(PS) since you seem to have drawn some connections with the sound systems. Here's some food for thought: you said that you had to turn up the volume in each "layer" which allowed you to put in the password (and get killed each time). But do you remember ever turning up the volume for the very last one?
I'll leave it at that :)
