# 2048 code originally from http://www.thetaranights.com/make-a-2048-game-in-python/
# there is a bug/missing logic that needs to be fixed where it will quit the game
# even if there is still a valid move left when the grid is completely full.
# but other than that it works.
# Originally this version used the Pimoroni UnicornHAT as the display. The source of
# which can be found at https://github.com/ukscone/unicornhat/blob/master/uni2048.py
# This version has been ported to use the Raspberry Pi SenseHAT as both the display
# and controls.
