Neotolis Engine

Minimalist game engine for Web/WASM

Tiny output · Zero magic · Code-first · C17

Philosophy

  • Code-first

    Game controls the main loop. The engine gives building blocks, not a pipeline.

  • Explicit over implicit

    You see everything. No hidden behavior, no magic behind the scenes.

  • Keep it simple

    Less code is better. Simplify further when possible.

  • Tiny size

    Every byte counts. Binary size tracked on every PR.

  • Set of modules

    Use only what you need.

  • Prebuilt assets

    Source formats packed into binaries at build time. Runtime loads packs on demand, no parsers.
