A ski simulator that runs in a browser tab. Nothing to download, nothing to sign up for, free to play. It draws on WebGPU where the browser has it, WebGL2 everywhere else.
Two kinds of mountain, both shipped on purpose. Kernel Peak (1.8 km, 524 m vertical), Mutex Ridge (2.8 km, 1,155 m vertical) and Endless Run are hand-built: park, pipe, rails, lifts, and a seeded line that never ends. Park City is the other half, imported from USGS 3DEP lidar and OpenStreetMap - 404 runs across 85.47 km2 of Park City, Brighton and Solitude, streamed in as you ski it.
Controls. A D or the arrow keys carve and steer, W tucks, S brakes and smears, and Space held then released is your pop. In the air the same keys spin and flip; J K L I are grabs. Gamepad and touch both work.
