Added a little boost image to it too, create like a flame that comes out of a rocket when accellerates or such like first and call it boost.png
f like anymore help with anything, give us a shout
perhaps create a sprite that looks like a star and replace the drawline commands (that create the star) with setspritesize commands
Hope it helps
Enjoy!!
