I wrote this program because I often am asked by people that know that I like to make games to make just a quick simple game for some reason or another. I always make a simple text based adventure game (like Zork, but simpler) and they are usually happy with it. Well, about 7 hours ago I was asked to make a game for somebody's birthday tomorrow, so naturally I started making yet another text based adventure game. Suddenly I realized that I basically had the code to make one of these games memorized... so I decided that enough is enough. That is how this program came to be. Here is a test file I wrote that displays how to make text based adventure games super quick:

MENU
This is a test!
Goto Win
WIN
Goto Lose
LOSE
~~~~~~~~~~~~~~~~~~~
WIN
You win! Play Again?
Yes!
MENU
No...
END
~~~~~~~~~~~~~~~~~~~
LOSE
You lose... play again?
Yes!
MENU
No...
END
~~~~~~~~~~~~~~~~~~~
END
-------------------

I will post any games that I make here (those that are not personal that is) and you can do the same. Also if you want me to make any improvements to my code, or add any features, just ask. This is one of the best kept projects I have made so far since it is basically the first one that I was able to just write, top-down, without having to make any corrections. Enjoy.
