natrix

A free snake game — play it in your browser, no install. 🐍Framework-free browser game runtime built on vanilla JS - fixed-timestep simulation, deterministic replay (seeded RNG + tick-indexed commands), explicit lifecycle state machine, and a swappable DOM/Canvas/Null renderer contract. Demoed via a local 2P Snake game.

From the README

English | 繁體中文 | 简体中文

Natrix is a framework-free browser runtime experiment built around a playable local two-player Snake game.

Compact runtime showcase: command-driven input, fixed-timestep simulation, deterministic replay, explicit lifecycle state, replaceable DOM/Canvas renderers, and live runtime metrics.

No any framework. No game engine. Just browser APIs, JavaScript modules, tests, and a small game surface that makes the runtime behavior easy to inspect.

You can switch the renderer at runtime from the control below the game.
