I enjoyed the ideas of the story.
I enjoyed this game. It lasted around 11 hours. That's longer than other people have mentioned, so I'll remove one hour for the mini-games, one hour caused by my confusion, and one hour caused by my slow-paced walking around to look at the environments. That means it lasted eight hours of regular playtime. That's not too short for this price. The previous game from this company, called "Conarium", lasted around eight hours, even though I was slow-paced when I played that one too.
I consider this game to be like a book that doesn't perfectly explain some details, to let us imagine our own interpretations.
In case people are worried, I will say this:
This GOG version includes the "Extended Edition" update.
