You drive a small rally car down a narrow gravel or tarmac stage seen from above, kicking up dust past crowds, caravans and farmhouses, against the clock and the ghost of your best run. Quick stage lets you pick one of six stages, such as Usui Touge in Japan or Harjunkulma in Finland, and set the direction, time of day and weather, while a career across four decades unlocks faster cars. Best on a computer: it needs a keyboard or a gamepad.
How the creator made it
The creator says Claude Code with Opus 5.5 wrote almost the entire game, starting with an Unreal Engine 5 desktop version made in about four days and then porting it to Three.js. The creator set the direction, played each build and fed their notes into the next round of work, while Claude Code assigned written briefs to agents working on different parts. The agents made the meshes with Blender scripts and generated sound effects and music with ElevenLabs. For the web port, they compared car handling against the desktop version with automated checks and used an autopilot to drive the stages.
