If you want a game that sparkles like horseshit, then just set a 4x8 blank image as your projectile.
If you want a game that sparkles a little more than horseshit, take a little bit of time and go into paint to make some basic projectiles. It's easy to rip projectiles from other things, just google image shit and then resize it, clean up a bit w/ photoshop or even paint, paste 4 times, rotate, paste 4 times, rotate, paste 4 times, rotate paste 4 times, add a drop shadow if you want, andddddd now you have a crappy projectile. But at least its somethin'.
