/**
* @author Andrii Pashentsev (https://github.com/andyps)
*
* Simple Rubik's Cube game done during js13kGames competition. Some code were cut to fit into filesize limits.
* Tested in Firefox, Chrome, Edge, IE 11
*
* Use mouse right/middle mouse buttons to rotate camera.
* You can also use left mouse button to rotate camera but outside the cube.
*
* To zoom camera use mouse wheel.
*
* Use left mouse button on cube to rotate its sides. Middle doesn't move!
* Happy solving!
