I'm gonna have to agree with SoundSD. I just setup something similar on a T2C. works like a charm, no need to worry about flags, can run on systems without an XP8.

If you want, you can put a reset button in a corner, put an animation on the reset button indicating you are starting over. You don't need the animation really. For the programmers we know what's going on in our heads as the program is running, but for the customers, its nice getting feedback. They really don't have any idea how it works.. they just push pretty buttons and things happen :).
