After finishing it, I understand more of what people can love about this game, still is not a game I can say its fun, specially when all the movement it's up to you to discover... do yourself a favor and search the movement and tips online (fuck five pebbles btw, the worst area in any video game I've ever played.) discovering everything alone is not rewarding enough to stand the frustration.
One thing that this game does that is indisputably good is the immersion, you fight for your life like you would in real life... also the OST is good too. But that's about it. IMO this game is good but not the masterpiece that people say it.
Expect good ideas in a game extremely frustrating and full of unfair shit.

the ending is amazing and a bit scary if you have thalassophobia tho...
