   https://emscripten.org/docs/getting_started/downloads.html

2. Clone the repository:
   git clone https://github.com/rafaeletc/wasm-sdl-gameloop
cd wasm-sdl-gameloop

3. Run make build-wasm or build manually:
   emcc src/*.c -s WASM=1 -s USE_SDL=2 -o public/index.js

4. Browsers doesn't support file XHR requests so you need to open index.html from a web server.
   Run make run-wasm or manually:
   emrun public/index.html

5. 🕹️ Use the keys ⬅️ and ➡️ to move the paddle, key R to start again.

6. You can run on terminal too, with compiler and SDL2 dependencies on place, just hit make build; make run

Todos:

• Improve Makefile
