Press t and hold the mouse down to make tracks. Press c to clear. Drag the finish and start out to the board. Press space to start your game. I made this in 1 hour and 15 minutes. I got the idea from windowsapple's forum http://scratch.mit.edu/forums/viewtopic.php?pid=492304#p492304 (Thanks, windowsapple!) I hope you enjoy this simulator! :D
