Windows version and new game resolution

I've uploaded a new version of the game with a downloadable zip to play the game on windows.

I've adapted the resolution to fit the game to be played on the browser, because the other resolution was intended to be played in mobile and didn't look good at computer screen. The mobile version that will be available in the future, will be played in landscape mode, so the game can be played nicely in both platforms.

Also I had to change the background because the other one did not fit well this resolution, so I've choosen a simple dark background that maybe will be updated in the future.
