Block Puzzle Game

In the game a random pieces of blocks fall down on the playing field. The objective of the game is to manipulate these blocks, by moving each one (left, right, fast down) and rotating it by 90 degree units, with the aim of creating a horizontal line without gaps. When such a line is created, it disappears, and any block above the deleted line will fall. When 20 lines are cleared, the game enters a new level. As the game progresses, each level causes the blocks to fall faster, and the game ends when the stack of blocks reaches the top of the playing field and no new blocks are able to enter.
