Funny Swipes app for iPhone and iPad

The Funny Swipes is a derivative of the original 2048 but it is not the same. More explicitly, it has the following additions:

1. There are three game modes which you can choice from settings
- The original Power of 2: Combining two tiles of the same value to produce their sum. Its same 2048 game. Use your arrow keys to move the tiles. When two tiles with the same number touch, they merge into one.
- The Power of 3: combining three consecutive tiles of the same value to produce their sum. Not surprisingly, this is pretty hard with the 3x3 board, although I found it
pretty easy to get 81. 243 is a different story...
- The Fibonacci sequence: combining two adjacent numbers in the sequence 2, 3, 5, 8, 13... (I omitted the two 1s in the beginning) to
produce the one next to the larger value. A tile can be joined with a tile that is one level above or below it. This is pretty tricky. Try it out and you will know what I mean.

2. There are three board sizes: 3x3, 4x4 and 5x5. The smaller the board is, the fewer cells you have, and the harder the game is.

3. There are three themes: I made a bright theme and a joyful theme in addition to the original one. In case you wonder how to do themes in iOS. (There may be a better way, but themes are verbose in
nature, because you have to specify all the colors, fonts, etc.)
