10 years ago on Android, button:active never goes away so when game ends, the button is still 'pressed'
on iOS, vh/vw units gets calculated on first layout and aren't refreshed on orientation change, so things aren't centred when switching between landscape and portrait the font isn't cached properly and resets to Arial on second fullscreen launch
gracefully adapt to screen size consider replacing the OANDA logo image by a datauri and inlining splash screen CSS to improve the time-to-glass rev the sound file (usemin issue of matching the sound file pattern in the minified JS file) nice to have: animated gif indicating to rotate landscape device into portrait
