Absolute masterpiece. Really innovative gameplay, coupled with a great message and big introspective moments. A puzzle game that is sort of a mixture between Inception, Portal and the Stanley Parable.

Great narration, great story, great puzzles, great journey. By the end of it I had chills all over me. It just keeps breaking expectations. The soundtrack is also amazing and contributes to the dreamlike feel of playing it.

It's all about perspective.
