You have one task: roll a snowball up a mountain. Seems simple, right? Only problem is there's no jumping, no checkpoints, and no forgiveness.
The controls couldn't be simpler: move left and right. You'll soon find out, however, that "simple" does not mean "easy." This game will push your cognitive ability to the very limit.
Over the course of your journey, you'll be kept company by your snowball companion with thought provoking dialogue such as "Ouch." and "That hurt."
