+		Enable Shift games. Shift is a brick game, like a mix
+		between Tetris and Crush Candy. The inspiration came
+		from a Shift game that was available for Android in the
+		F-Droid store. The original game source code still here:
+		https://github.com/boombuler/Shift/ but the game only works
+		for old Android versions (4.x).
+		NOTE: The source code here is not based on that code from
+		above github.
