Naw, don't worry, take advantage of whatever features you want for the sake of learning and creating a good program. If you only plan on distributing the application so that others can play it, then just attach the executable.
Decent game, though it could be a bit more organized (and neater). One way of improving your code would be to organize it into classes, which you can find three great tutorials on near the end of the Turing Walkthrough. This would also enable you to avoid partially nasty things like global variables for the most part and code repetition. Your variable naming could use a little work, sincewritingeveryvariablenamelikethisdoesnthelpreadability, insteadYouCouldUseCamelCasingWhichHelpsMuchMore or some_people_prefer_underscore_spacing.
Also, a variable to keep track of some sort of score would be nice.
