I recently (Sep 99) made some changes to tetris's handling of keys to (hopefully) make it more compatible.
If you're using a small bw display, such as a 640x480 monochrome laptop, use this version.
You might ask why this Tetris doesn't have a preview of the next
piece or rotation in both directions. The answer is because I don't
like it. You may disagree and
play another Tetris.
Or yet another one.
