The world outside William's door is enormous. Rain-slicked mountains, towering fir trees, and hidden caverns await your exploration. Tapping [shift] will bring up your objectives screen, and your map when you finally gain one. Use the [WASD] or [arrow] keys to move around, and tap [up] or [W] to leap. Don't be afraid to fall, because Sly can take anything you throw at him. In fact, the silky-smooth control scheme practically begs you to push it to its limits and run, leap, and maybe even soar your way to discover every hidden item. The game is a stunner, with a haunting soundtrack and incredibly smooth visuals.
