EquiRail Spire

Walk glowing ice rails on a polar spire. Left and right fingers set opposing lean forces; their difference tips you. Closer pressure means higher per-second symmetry score. Dual upward swipes nudge speed at greater risk. Frost-slip events spike friction changes; fall and the segment ends with no respawn. One-finger bracing zeroes symmetry. A frost-free clear earns a mirror bonus. Narrowing rails raise the challenge.
