Underlayer 1024

Further development of 2048 idea.
Game has 2 layers with tiles fields: the bottom Underlayer and the upper transparent layer. When some tile on the upper layer appears over the tile with the same value on the bottom layer, these two tiles merge, and the resulting tile receives the value of the sum of two merged tiles.
Move tiles on both layers left-right, up-down, by moving the cursor over the screen, to merge equal tiles. Try to get this way up to 1024, to win the game. And each next level is more erotic!
Controls: Move (drag) cursor over the screen (mouse or finger).
