Short Review:
Buy it. Buy it now, stop reading, play it blind. I beg of you.

Long Review:
Genuinely the most amazing survival horror experience i've played in years. The story, the art, the music, the characters, it just works. Its so well done, hard to believe its made by only 2 main people. My friends suggested this to me, and i was expecting it to be good, but jesus christ. Its so much better than anything i expected, and boy the wave of emotions the endings give you is heavy. I've already recommended it to more friends, and you should too. Now, if you'll excuse me, im off to 100% the achievements, and play the other endings by myself. Because good god, the developers deserve it.
Vielen Dank Yuri Stern, Vielen Dank Barbara Wittmann, für euer absolutes Meisterwerk.
