Just noting there are a few problems with the game itself,
1. There are a few bugs with a extension you are using ( socket server?).
2. There is a null error in one of your actor events or behaviors.
3. You referenced Actor "car_01 27" as a actor type in some code.
4. The platform requires OGG sounds: Racing Intermission Loop Upbeat, Import your sounds as OGGs
This is what caused the break ( html5):
Error: Resource file not found : Config/preloader-badge.txt,
For some reason Stencyl is having a problem with your custom preloader, try removing it.
