A falling blocks game that I wrote to demonstrate usage of HTML5 and Canvas to make an interactive game that runs in a web browser. Use the keyboard left and right keys to move pieces, press the up key to rotate a piece, and press the down key to drop a piece. Dropping pieces and completing lines increases your score. After completing every 10 lines the speed of the game increases which makes the game more difficult as the player progresses.
Web browser must support HTML5 and Canvas
