Maybe make it about a trip, and if anything goes bad then you will have a bad trip? Give it [psychedelic visuals, but you have to complete tasks while trying to navigate through the visuals. I like your idea. Sounds cool.
I've come up with the idea of it being a visual novel-esque game inspired by the movie Wonderwall from 1968. It'll be about a girl living in a dreary town but she sees nothing wrong with it until one day she feels odd feelings of discontentment and seeks peace. I won't spoil too much of what I want the game to be about.
