I watched it when it just came out and I binged it in a night or 2 so I can definitely recommend! I think it lives up to the hype, but I don't think it's a show for children/teens (even though they are creating the hype). I would say it's similar to Alice in Borderland.
However, it can be a bit bloody/gory. I listed the gory parts down below without spoiling too much:
shots in head/body, lots of blood throughout the series, a cut out eyeball, organs in body that's been cut open and brains on the floor
If you're sensitive to animal gore: a dead fish is being chopped for a split second.
