You can’t fix stupid.
Imagine PHG being such a simple game, is too mind blowing for some people that tapping a sequence of inputs showed through UI prompts is too big of a challenge.
Portal is a hell of a game, but is problem/puzzle solving. 90% of the population is not going to be able to progress much on it.
See how games like DOOM went from repetitive boring FPS to puzzle solving “a lá Resident Evil” and then went back to repetitive boring FPS but “with good graphics” because thinking is just hard for most people.
