Even Better Sequel / Sequelitis: Or remake, rather. Slender: The Arrival has been shown to do functionally everything better than its predecessor. On the other hand, the plot has been criticized as too vague and the length is said to be a bit too short.
That One Level: The abandoned mine area, where you have to turn on the generators seem frustrating to some since not only is Slenderman trying to get you but also his proxy who tries to chase you down and if it catches you, it cripples you making it a lot harder to get away later. Fortunately you can switch the modes on your flashlight to stun it, but the game doesn't tell you that. Heck even after you turn on all the generators, it can still get you while you're waiting for the elevator to rise.
