Playing alone is scary at first, but later you get used to it and get through it easily.
It seemed to me that the game lasts for a maximum of 50 hours - there is nothing further to do there, although a large-scale update was recently released.
On the plus side: a lot of maps, a lot of ghosts with their own characteristics, a large number of items to search for (appeared after the update), there are also achievements.
Of the minuses: the game gets boring quickly.
