STUPIDROBOT - delay the boot button
the issue is, if you click boot too fast, sometimes the game stucks at loading page, depending on the netowrk status. So I delay the boot button for 2 seconds.
STUPIDROBOT - fix the navi bar font issue
by specifying the font-family explicitly
STUPIDROBOT - tune the animation of boot button
the previous one flash too much time and makes my eyes feel uncomfortable
