Tumbledown

Tumbledown is a free racing game made with AI by @maxify, and you can play it right here in your browser.

Tumbledown is a chaotic arcade downhill race where three homemade contraption machines careen down a giant alpine mountainside at the same time — and one of them is yours.

Pick your machine in the workshop: the balanced copper boiler kart Boltbucket, the blazing-fast but fragile one-wheeled Gyro Gizmo, or the slow, nearly indestructible bathtub racer Clunker. Then it's 3... 2... 1... GO — gravity does the rest.

Weave through boulders, launch off wooden ramps, and grab golden bolts to hold your rattling machine together. Every crash knocks parts loose; run out of integrity and you tumble apart in a shower of springs. Beat both rivals to the checkered finish gate to win, and chase your best time down the mountain.
