Shear Line is a real-time 3D flight physics game — you're not the pilot, you're the airframe itself, sent through a canyon test corridor to find out how much structure it takes to fail. Steer through a rising series of pressure gates: clear one cleanly and nothing happens, clip the edge with a wingtip and that wing takes structural damage. Push it far enough and the wing physically snaps off — a real rigid body that tumbles and falls away behind you, not a fade-out animation.
Losing a wing doesn't end the run. It ends the easy part of the run: the plane pulls hard toward the missing side, steering gets duller, and top speed drops — you have to fight the drift with every input from then on. A Field Patch Kit (one per run, coins or an ad) can restore a lost wing if you want to keep pushing. Lose both wings, or fly straight into a wall or a rock spur, and the airframe reaches its limit.
Come back daily for the Daily Corridor — a fixed test route seeded by the date, so every player faces the same canyon. Keep the streak alive for climbing coin rewards, and spend coins on paint jobs and cockpit charms that unlock mostly just by flying well.
How to play
- Steer with arrow keys/WASD, or drag on touch — thread the gate openings.
- A gate opening shrinks the farther you fly; clipping the edge damages that wing, hitting the solid pillar ends the run instantly.
- Horizontal bars force a climb or a dive; solid rock spurs must be dodged entirely.
- At 100% wing damage the wing physically detaches — flying degrades a lot but keeps going.
- Zero-damage flights and clean 200m stretches earn bonus coins on top of distance.
Tips from the leaderboard
- Gate openings glow amber early and shift to red as they narrow — read the color, not just the gap.
- After losing a wing, over-correct slightly against the drift rather than centering — the pull keeps building the longer you fly.
- Save the Field Patch Kit for after Load Test Canyon (800m+) — the payoff on a long run is much bigger than using it early.
- Play the Daily Corridor every day even on a rough run — the streak reward table pays out for seven days straight, then loops.
