 - Has **completely NO external dependencies**, not even rendering or IO, that is left to each platform's frontend, but each frontend is very simple. Uses **no dynamic heap allocation** (no malloc).
 - Can fit into **less than 256 kb** (including all content, textures etc.).
 - Uses **no build system**, can typically be compiled with a single run of compiler (**single compilation unit**).
