Squash 2.2

Introduction
------------
Welcome to Squash 2, the only pong game for the TI-83 that runs on the graph screen and is fully written in TI-BASIC! (At least the only one I know.) It has in-game instructions, saves your hiscore and is very nice to play! And if you plan to start programming games on the TI-83, maye you can even learn something from it.

Installation
------------
The installation of Squash 2 is very simple: just send the file 'Squash2.83p' to your calculator. Then you can run it from the PRGM menu or from AShell or a compatible shell, like SOS.

Playing the game
----------------
The concept is so simple that it is hardly worth explaining, but I'll do so anyway. At the bottom of the screen you see your racket. You can move it with the arrow keys. The goal of the game is to keep hitting the ball, that bounces around the screen, with the racket, so that it doesn't fly off the bottom of the screen. For every hit you score a point. Each time you score 5 points, the ball will speed up. At every 15 points, the ceiling drops and the ball goes slower again.
Squash 2 will automatically save your hiscore, and notify you when you broke it.

Uninstallation
--------------
You must be kidding, right? Throwing such a good game off your calculator! But if you're determined to do so, simply delete the program 'SQUASH2' and the list 'SQU2' (in which the hiscore is saved). There. Now you've done it. How could you.

Squash
------
At the time of writing, there are Squash 1, a TI-BASIC version on the text screen, Squash 2, which runs on the graph screen, and Squash 3, which is written in assembly and runs on the graph screen. They are all available from www.ticalc.org.

Source
------
There is a commented version of the code included, called 'Squash2.src.txt'. If you have any questions about how the program works, or if you're just curious, have a look at it.

Legal stuff
-----------
Of course this game can't harm your calculator, but if it does, I reject all responsibility.
