Can Someone Help Me Determine If This Is a Bug or Me?

I don't know if I found a bug or not.

I have a tiled background set to resize to a proportion of the window and be centered.

On my desktop it works perfectly, but when I try android (chrome) it's off center.

You should put the exported html project in the Public folder of your dropbox account and link it directly from there. If you don't have a public folder already just create a new folder and name it "Public".

Thanks, I just did that. I'm new to dropbox.

Ok, now go your account at dropbox.com, find the html of your game, right click, press copy public link and post it here. Now people will be able to access your game.
