Perpendicular

Perpendicular is a reflex runner about dimensions. You race forward as a point on a line, and every obstacle is a solid shape, but you only meet the slice of it that crosses your world.

On the line, anything in your way is a wall, so add a dimension. As a plane you see each block's flat slice and steer over or under it. In 3D you see everything whole and can go around it. When a gap is thinner than your body, drop back down and slip through.

Fewer dimensions pay more: time as a line scores x3, as a plane x2, and in 3D x1. The best scores come from staying as flat as you dare.
