Kaigen's hello world is just 16kB — the JS entrypoint is bigger than the whole engine

gdechichi · x · 2026-10-21

A dev shared Kaigen's "hello world" empty project: the entire engine (game.wasm.br) is only 16kB — smaller than the project's JavaScript entrypoint.

The screenshot shows main.js at 13kB, worker.js at 63kB, and mainworker.js at 81kB, all dwarfing the stripped engine itself.
