Slayer, the Game

Certain calculators allow you to program games and other things onto them. If you have a programming calculator, you can program this Buffy game I wrote into it. Math class will never be boring again!
(Note: This game has only been tested on the TI-83 Plus calculator by Texas Instruments.)

Please replace all question marks with the "store" or "arrow" symbol (the button right above "on"). Also replace the >= with a "greater than or equal to" sign and all <= with a "less than or equal to" sign.
