power of two

This is another android port of the great occasional game "2048". The original game was made by Gabriele Cirully and uberspot did an android port.

Unfortunately the game slows down the more the bigger the tiles are, and is no fun anymore beyond the 16384 tile. So I began to write another port.

Besides the performance, I added three difficulty-levels. They differ in the number of undo-steps and the probability of fours appearing instead of twos.

Have fun! Christian Wahlmann
