Weird game. Feels more like a graphical showcase than a game.
Good points:
* Amazing graphics
* Music is excellent
* Quite scary in places, psychological horror
Bad points:
* Large parts of the game are just walking in slow motion while dialogue plays. Either walking or climbing or crawling through narrow caves and you do it really slowly too.
* Puzzles are repetitive and simple
* Only 7 hours long.
Gave it a 5 / 10 because although large parts are extremely boring - mainly walking from cutscene to cutscene, there is a brilliance about it. The excellent graphics certainly helps and the music adds to the moods well.
I should note that I only realised you can roll while fighting to avoid certain attacks 3/4's of the way through the game due to there being zero on screen display or tutorials.
