The game doesn't seem to run for me in the browser.
Same I had that problem; I do not know how to fix that.
If this is a unity game. You would need to create a different build for it. Zip that build and then upload it to your game page. We just found a tutorial on Youtube and followed the instructions. You need to do a build for each platform.
I did that and for some reason it did not work; I guess I will have to stick to windows build.
