General idea: Something of a cross between Galaga/Space Invaders and Tetris. Blocky shapes descend from the top of the screen, and to destroy them, you shoot blocks to fill in the gaps and make a rectangle. There can be two modes: an endless mode where you try to fend off increasingly challenging waves until you miss three; and a timed mode where you just have to clear as many enemies as you can within the time limit.
