A vertical wall fills the right side of the canvas with ledges marked every meter. The climber dot stays fixed on screen while the wall scrolls past as you climb. Each detected upward burst of motion (centroid moving upward sharply) gives the climber a velocity boost; gravity pulls it back down constantly. A dashed gold line shows your previous best height. 60-second round.
