Description
Most online language playgrounds stop at compiling code and printing text. But C3 contributor Manu Linares wanted C3’s playground to go further.So here it is: a playground that compiles and runs interactive graphical programs — including games and Raylib-based demos — directly in the browser.

Could you build this?
Partial While a code editor UI is simple, compiling a systems programming language (C3) and executing interactive graphics (Raylib) and audio client-side in the browser requires WebAssembly toolchain integration.
What it would actually take: Requires compiling the C3 compiler itself to WebAssembly or running a sandboxed serverless container execution farm, coupled with Emscripten/Wasm bindings for Raylib/OpenGL and WebAudio. The difficult part is compiling user code targeting WASM/WebGL directly in the client or streaming execution frames back with sub-second feedback loops.
