From CBC:
Little Wally Ball-y Ball is a game focused on slope. The goal of the game is to roll Wally Ball-y down Goo, who is dragged into shape by the player, to land on a target. The player manipulates the shape of Goos body and then Wally Ball-y rolls down Goos body. By watching Wally take the path that the child has created toward the target, the user will gain a greater understanding of slope through various irregular geometric shapes, using visualizations and trial and error.
