I'd call it "overbaked" - the ideas are great, with the switching of characters and mental space to solve cases and changing the structure of levels with shutting off/turning on the lights, the non-linear narrative (you can technically do the stories in any order) etc... but as a whole it just feels... too much.
Too slow, gameplay-wise, really a bit overcomplicated - the lore is so byzantine I'm literally completely lost - and keeping up the momentum feels a bit like chore to me. The game is really good on paper, but it isn't that much fun as a game. IMHO, that is.
