How it automatically opens in the "fullscreen"(browser tabs still visible)?

That is unusual. On all the devices we tested it defaults to 1280x720 and does not default to full screen. Could you send me a screenshot of how it looks on your end? I'd really appreciate that. Also did you try another browser than firefox? I mainly use firefox as well but none of the issues you mentioned have been apparent on my end. It also worked fine on my Ubuntu firefox as well.
Yes it works now. I also understood why I couldn't change gravity when had fuel. The red blocks don't allow to change gravity when you are in them. But it isn't obvious because you also used them as decoration... You shouldn't use it as decoration or you should emphasize it somewere in gameplay for example text label
