William and Sly is is a platform-based adventure game. Developed by Kajenx and published on 20th of July, 2009.


You play as Sly, a fox with a goal to re-operate 13 runestones by which his master, William, used to teleport to an old storage cave. 

In order to re-operate a runestone, Sly must gather a certain number of fairyflies, being careful of darklings who target them. Darklings hide in the bushes and mud and give a surprise attack. 

Whenever you light a runestone, you'll get a charge that'll banish any darkling around you.

Throughout the game, you collect mushrooms, either found on the ground, in chests you open with keys you must find or turn switches on, which will grant you a path to other mushrooms. The game is full, as well, with secret tunnels to look for. 


WASD or ARROWS to move.

SHIFT to view the status screen.
