Tandemonium

What it is

Tandemonium is a multiplayer game that @petegordon made for Vibe Jam 2026, pitched as multiplayer on a tandem bike, with gyro tilt for balance. The home screen shows speed, distance, the checkpoint, and the tilt of both you and the bike. You steer with A/D and pedal by alternating the left and right arrows, or use a gamepad (left stick to steer, A/B to pedal); the screen says a gamepad with gyro is preferred. Tap "TAP TO RIDE" to start. The jam rules require at least 90% of the code to be written by AI; the jam page doesn't list which AI tools were used.

Who it's for: friends who want to test their teamwork on a shared bike.

Before you start: under Vibe Jam's rules it's free to play in the browser with no sign-up. Multiplayer goes online. Keyboard works, and a gyro gamepad is preferred; the page doesn't specifically say it supports phones. The address on the jam card is a preview build (it contains pr-preview) and may change later. The pages are in English. No age rating is given.
