Outstanding visual quality and atmosphere, while dark and fairly minimal. Interesting and creative ideas are presented throughout in the form of effects or 3d models. The music is of quality as well and provided some tension to a dark world.

I would like to see an option to adjust resolution and texture quality if this was to be expanded upon. My PC could barely run this and I have a fairly beefy PC. 

I would of liked to see more in terms of mechanics or puzzles. While beautiful, it was somewhat boring to play.
