Use the arrow keys to move. Collect data cards (green and yellow rectangles). Beware of Stormtroopers: you'll die if you touch one! The popping noise means the storm troopers are about to reverse direction. Also, it helps (a lot) if you play with the sound on.
Sorry, when I first made this it was really bad, and I'm only fixing it now. :/ Anyway, it's a work in progress, so if its glitching like there's no tomorrow, that's because it's not finished.
