Tandemonium

About Tandemonium

Tandemonium is a party-physics racing game where you navigate a tandem bicycle toward a destination. You can play solo or join a partner in local co-op, with one person acting as the captain in the front seat and the other as the stoker in the back. To move, you must alternate between left and right pedals while steering to maintain balance. The game supports various control methods, including keyboard inputs, gamepads, and phone tilt motion. If you lean too far, you will crash, so careful coordination is required to reach the finish line.

This game stands out for its focus on cooperative physics and shared movement. It is well-suited for players who enjoy lighthearted challenges and social gaming. Sessions are quick and arcade-style, making it easy to jump in for a short round. The game is fully functional on mobile devices using tilt controls. This project was created using AI as part of the Vibe Jam 2026.
