WASM-4 15 games
WASM-4 is a free "fantasy console" built on WebAssembly: an imaginary handheld with a 160×160 screen, just four colours, a d-pad, two buttons and 1 KB of storage for saves. Its limits make for small, sharp games, written in languages such as C, Rust, Zig, Go and AssemblyScript. These were made by independent developers and released under free licences. They run in the official WASM-4 runtime, with saves kept in your browser.
