A decent second series with a collection of nightmarish games as you would expect. Worth watching if you liked the fist one, but the following irked me (some spoilers):
1. Main characters becoming essentially invincible towards the end. So many characters surviving from absolutely horrific injuries after being left to bleed out while Arisu plays the longest game of croquet ever.
2. Backstory flashback filler. There was too much of this, and it felt shoe-horned into a show about horror and puzzles.
3. The ending will probably be deeply irritating for some (I thought it was fine though, and I did enjoy the way they toyed with it).
