As a long-time fan of the Amnesia series, I have to admit I am in love with Amnesia: Rebirth. The game did not disappoint me in any way.

The story and lore is incredibly rich and deep, and the game does a great job of revealing it to the player piece by piece.
The environments in Amnesia: Rebirth are as beautiful as they are terrifying. There were quite a few moments during my playthrough when I wished there wouldn't be any threats around just so I could take in the beautiful creepy and desolate atmosphere my surroundings had.
Speaking of atmosphere... this has got to be my favorite thing about this game. During my 9-hour playthrough, I was CONSTANTLY on edge. I can honestly count the amount of times when I felt safe on one hand. I don't think I've ever felt as exposed, vulnerable and helpless as I did in Amnesia: Rebirth. This was true even when there weren't any monsters around, and that, in my opinion, is a sign that Frictional Games did an incredible job of building up the tension and letting the player's mind do its own thing.
Tasi, the main character, is very likable and I felt connected to her very quickly. She frequently comments on her situation, thoughts, feelings and memories, which - to me - is a very welcome addition compared to the past Amnesia games, where the protagonists barely said anything. It really helped Tasi feel like an actual person, with a painful past, sincere emotions and hopeful dreams.

However, if there's one thing I didn't like that much, it would be how quickly the lantern's fuel ran out. At one point my lantern was full of oil and I don't even think it lasted me 2 minutes. That is a bit of a problem, because 75% of the game takes place in very, if not completely dark surroundings. Thankfully the game introduces an alternate source of light in the form of matches - and there's plenty of them scattered around the game's many locations.

To sum up, I love Amnesia: Rebirth and I can't recommend it enough to anyone who likes a good horror experience. Do catch up on the lore of other Amnesia games first, though!
