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.
