Sunny Kart - Motion Break

Take a short, sunny driving break with Sunny Kart. Cruise through colorful 3D scenery with six karts, three laps, and gentle road assistance. Motion is selected by default on desktop. Use a camera to play while seated: - Tilt your head once to change one lane. - Lean your shoulders left or right to turn. - Shrug both shoulders for a short boost. - Return to a relaxed position before repeating an action. Choose Meadow Cruise, Lakeside Flow, or Sunny City Circuit. The two wide-road routes arrange acceleration, left and right lane changes, and alternating bends into a relaxed driving rhythm. Road assistance helps keep the ride on track. Keyboard controls are also available: W or Up to accelerate, A/D or Left/Right to steer, Shift to drift, Space for nitro, R to return to the track, Esc to pause, and F for fullscreen. Click the toolbar icon to open the full game in a tab. Clicking again returns to the existing game. Play locally without starting a server: the game, sounds, and motion model are included in the extension and work offline. Camera permission is optional and is requested only when you start motion driving. Camera frames and motion landmarks are processed on your device, never recorded or uploaded. The extension does not request microphone access, read browsing history, inject into other websites, or include ads or analytics. Settings and best times remain in local browser storage. A desktop computer with WebGL2 and hardware acceleration is recommended. For motion play, keep your head and both shoulders in view with steady lighting. Keyboard play works without a camera. This is an entertainment game, not a medical or fitness assessment. The game is free to play. The menu includes an optional "Buy me a coffee" entry with a WeChat QR code and a suggested CNY 9.9 contribution. Support does not unlock features or affect gameplay; no payment is required.
