Sacred Line is a free first person dark adventure/surreal thriller with story-driven explorative physics-based gameplay, black-white-red BD style and abstract non-cliche plot.

The game wasn't to bad for the most part. I had a hard time following the story and the game ended way before I thought it would. Also I found it hard to see in the desert as no bricks glowed for me. On a good note I liked the suspense and the demon looking figure.
