Rules of 2048: You start with two 2 blocks. Use the arrow keys to move them, BUT: when you press a key, ALL the blocks will move that way. Try to get to 2048 or 4096!! :)
So, what I mean by extended is that there is a 4096 block that I added. Please support me, this took so long... Plus I messed up halfway so I had to restart. Hehehe...
