Shiftshape: Now available for Windows + minor polishes

Shiftshape v0.0.1 is now available for download on  Windows (but only on x86 64-bit architectures).

Several changes have been made to both the web and Windows versions of the game:

• Loading time on web has been cut down slightly.
• Added a back button on screen for mobile devices. (Back button on Android still currently doesn't work for web.)
• Fixed an issue where the game would freeze for a few moments when first shifting.
• Fixed an issue where   the   slider would not play audio or the text value would not change if the slider was dragged via mouse or touch.

Current goals:

• Add more levels
• Make game available on Mac, Linux and mobile devices
• Make the back button on Android work properly for the game
• Reduce loading times a noticeable amount
• Make the settings an ini file so people can edit it outside of the game
• Get the neighbours' cat out of the garden
• Change the icon on Windows to not be the default Godot icon
