It is a walking simulator with some puzzles you have to solve along the way. I got stuck a few times and had to view youtube videos to progress. The story is interesting. It took me longer than the average person will take playing it. I received the game from a Humble Choice bundle.

The game should take less than 10 hours, it took me more as I accidentally left it running when I left my apartment for a period of 2 hours. Some people may finish it in less than 5 hours...

It could be frustrating for people as it was with me, but in the long run it was an interesting journey to experience...
