seriously, I have it sitting on my PS4 at like 95-100% in everything after one playthrough when I first got it, except Area 5 because I really cannot be bothered to run it like 5x in a row to remember all its little tricks. I'll probably buy it again when I replace this PS4 and there's a re-remake.
If you haven't played Polybius or Sayonara Wild Hearts, I can highly recommend them - they are both games that stroke their fingers gently across the same places that Rez tickles.
