Tetris (Sinclair Spectrum)

Nice graphics for its age, but otherwise one of the weakest Tetris implementations ever made. Features the music of Tetris (Commodore 64). Background graphics may look too similar to the blue or cyan pieces but they can be turned off. Ignores movement if rotation is used simultaneously. Polls inputs at the same rate as the active piece is falling down. If movement / rotation is used 2 polls in a row, then the active piece is also moved / rotated 2 times in a row. That means in level 9 the active piece will most likely move by 2 or 3 columns although only 1 column is intended, and at level 0 some inputs may be ignored.
