On thin ice, tap twice to mark a span, then check it against the floating ghost ruler. Stay inside the tolerance band to keep the run going; miss and fractured ice builds until the session ends. The pace is calm and measured—less about rush, more about clean spacing. Bands tighten later, the start point drifts, and the second tap can race a short clock. Ideal if you like short decisions made with two precise touches. Portrait, light to launch, clear fail states, and quick retries. Visuals stay cool: pale ice cracks and soft cyan highlights that read well on a phone without visual clutter.
Two taps set ice length; land inside the ghost ruler.
