How to Build EXE (Windows)

• Add MinGW GCC 11.2 bin folder to your PATH.
• Add SDL3-3.3.4-win32-x64.zip folder to your PATH.
• Add SDL3_mixer-3.1.0-win32-x64.zip folder to your PATH.

How to Build WebAssembly

1. Set up Emscripten 4.0.15 and Node.js
2. Install http-server globally:

npm i http-server -g

3. Configure paths in config-web.bat for your SDL3 libraries.
4. From the project root, run:

config-web
build-web
http-server -c-1

5. Open your browser and go to http://localhost:8080 to run the app locally.

Note: You can also run the WASM app on Android via Wi-Fi using http-server. After starting the server, it will show local URL addresses — just type one into your mobile browser.
