ABC-Tetris

A slightly unusual variation on classic Tetris. The player arranges falling blocks of various shapes, trying to keep the height of the fill as low as possible until a certain time has elapsed. Arranging a full row causes it to disappear, which lowers the height. When the time is up, the number of unfilled levels on the board is counted and the game calculates the points earned by the player based on this. Additional points are earned by clearing rows and accelerating the downward direction of the blocks. At each level, the player receives a parachute, which allows them to briefly stop the block in place by using the upward direction. The game ends if any block touches the top edge of the board.
