I've just put up a downloadable version of the game! 

To play, all you need to do is open the index.html file.

With this download, you'll get access to:

• Higher res background image and sprite
• Access to the game files and source code
• Fullscreen mode with responsive desktop web version

Do note that this is still not ver mobile friendly, though! I will need to figure that out some other time, (if ever)
