Grotto — Bumper Run

Take the wheel of a bumper cart in Grotto — Bumper Run, a cave-driving game framed by dark rock, luminous crystals, and a turquoise lagoon. A glowing track edge guides your route through the Lumen Cavern.

Collect 12 glow shards around the cavern, with a shard counter, bump tally, and run timer tracking your drive. The on-screen objective also invites you to bump a rival for an instant boost refill.

Drive with WASD or the arrow keys, press Space to boost, and R to reset. A speedometer, boost meter, and compact loop map keep the essentials in view.
