Game dev workflow as :

2. Switch Platform to WebGL
3. Import this asset
4. Open DemoScene and add scene to Build Settings
5. Click "Build" Button to build WebGL project, the output directory **MUST** named "web"
6. Test the game on localhost
7. Zip the "web" directory and upload the .zip to Facebook via web hosting tab
