2048 Tamizh

This is a yet another 2048 kinda game. The game has a 4x4 square grid. A random tamizh vowel appears on a random tile of the grid for every move of the player. The job of the player is to swipe the screen (up | down | left | right) so as to move the tiles. When two identical tiles occur to move, they merge into one tile. The merged tile will take up the next vowel of those tiles that made the merge previously. Whenever the player reaches a merge that displays the last tamizh vowel, he/she wins the game. If the grid is full of tiles and no other move is available, the player is suppose to be on the losing side.
