Jack Frost, scowling star of the final game in Nitrome's informal 2007 winter trilogy (after Thin Ice and Snow Drift), is happiest when he is cold. Your job is to turn 40 levels of autumn-colored blocks and ladders into an arctic wonderland in this new arcade action game. Control Jack with the arrow keys: [up] to jump, [left] and [right] to walk, [up] and [down] to climb. Simply step on blocks or climb ladders to freeze them.
