I am sorry to say.

So I said there was controller support. To do this I used a Game Engine based on Scratch called "Turbowarp." And I converted the .sb3 (Scratch Project File) to.HTML (HTML5) using the Github project "HTMLifer" basically it turns Scratch games into an HTML browser game. And this may have disabled the gamepad code so when I tested it and it would not let you. I am deeply sorry for the inconvenience.
