it's untenable for actual gameplay that the wall completely changed location and orientation.It would in an SCP-themed game. Or dreamscape/Inception themed one.
Hell, "you're trapped in Doom-like dreamscape, escape before you lose your mind" is a very interesting pitch for a game. Basically take this Doom thing and make walking though a specific, unique-looking doorway from the original game to be the victory condition - the player's job would be to coerce the model to generate it, while also not dying in the Doom fever dream game itself. I'd play the hell out of this.
(Implementation-wise, just loop in a simple recognition model to continously evaluate victory condiiton from last few frames, and some OCR to detect when player's hit points indicator on the HUD drops to zero.)
(I'll happily pay $100 this year to the first project that gets this to work. I bet I'm not the only one. Doesn't have to be Doom specifically, just has to be interesting.)
