The cart never stops. Read the sign, then steer into the lane with the right answer.
Steer: tap the left / right half, or A D / ⬅ ➡ · Jump: swipe up, or ⬆ / W · Duck: swipe down, or ⬇ / S
Pick what the signs ask you:
🟨 Jump the low barriers. 🟥 Duck the red beams. 🪨 Steer round the rocks. Every one is signposted early.
💎 Gems = coins. 🧲 magnet · 🛡️ shield · ⚡ boost. 🔀 Every third gate is a FORK: the right answer picks a new tunnel.
A wrong lane or a crash costs a heart, but the cart rolls on.
