Au Sable is a game by the maker of All of Our Friends Are Dead, Amon26, and appears to be at least a spiritual sequel to that game. Fans of the previous game might enjoy the new one. For those who didn’t play that one, they are both platformers which focus on delivering dark and creepy feelings.
There’s more variety than the first game, and the controls feel tighter, and the art is just as nice. My only complaint is that the mouse cursor is off by default and the only way to learn how to turn it on is in the ReadMe file (which I missed and played through the game with that difficulty).
Again, you can get a taste of the game from Ortoslon’s playthrough if you’re sleepy or unconvinced by this review.
