xTetris v2.0 Written by Daniel Singer
15 December 1989

Description:

xTetris is a video game much like the popular TETRIS, but shapes are composed
not only of squares, but of tirangles, as well.  If a triangle fits against
another triangle, as to complete a square, the triangle will slide off the
second if it can.  The "x" particle which falls periodically is your gift;
it will destroy the first particle it touches.  Use it to clean up after
yourself.

How to play:

Use the numeric keypad.  Arrows move the falling object left and right,
the up-arrow pauses the game.  You may rotate the falling object clockwise
using the 5 key or the INS key.  To turn of the sound, hit the printscreen
key (don't use SHIFT when you do it).  If you wish to end the game early,
hit ESC.  Space bar drops the falling object (you lose control, but gain
points for dropping).
