[DEMO Patch 4] Quality of life improvements

This patch brings quality of life improvements to the demo of Pipeworks Puzzle:

• An option to zoom in and out of the grid arena has been added (click on the arrows sign on the left to zoom in and out)

• Controller support added. To change the cursor speed between fast and slow, press either of the shoulder triggers. Use either the left or the right joystick on your controller to move the cursor. Press start to pause in game. All other buttons can be used to click.

• Slight improvement to the visual look of the mute/unmute and next song icons in game.

As always, if you have any feedback, bug encounters, or feature request, please let me know via Discord (link below) and I will be happy to hear about it :)
