Demos

Showcase arena

A platformer under a living sky: weather, a day and night cycle, lights, bloom, a text HUD and synthesized sound.

Runs on WebGPU in this page, with sound.

About this scene

The engine's long-running showcase scene. Storms roll in and clear, the sun and moon cross the sky, rain, snow and lightning come and go, and lanterns glow at night, while you run and jump through it collecting coins. It is the same source file the desktop example runs; only the host call differs.

Controls Arrow keys or A and D to run, Space to jump. Click the scene first so it has the keyboard.
