A keepy-uppy game with a snowman's head for a ball, and the Xmas champion is whoever keeps it up longest. The mouse moves your striker and the task is simply to keep the head from touching the ground, which sounds trivial and is not — each hit sends it higher and less predictably, so the longer a run goes the less time there is to read the next bounce. A single mechanic, a score, and a seasonal excuse for both.
