Blasteroids is almost done! I have a working laser, I've got the spaceship to move, and soon my first game on smileBASIC will be done! Thanks to everybody who helped along the way!

Does anybody know how to make enemies home in on a character?

Does anyone know how to get sprites to move?

Does anybody know how to load custom sprites?

I need help! I can't figure out how to make it to only react to certain buttons. Right now if I press any one of the ABXY buttons it beeps.
