Space Invaders like game

They aren't ASCII characters, although that's what they're meant to look like. I don't have Assembly, so I just drew the bullets with LINE and CIRCLE statements.

Code:

IF bullet$ = "yes" THEN
   LINE (bulletx, bullety)-(bulletx, bullety - 10), 3, BF
     IF powerup$ = "bomb" OR powerup$ = "super bomb" THEN
       LINE (bulletx - 3, bullety - 5)-(bulletx + 3, bullety - 5), 3
       LINE (bulletx - 2, bullety - 3)-(bulletx + 2, bullety - 7), 3
       LINE (bulletx - 2, bullety - 7)-(bulletx + 2, bullety - 3), 3
     END IF
     IF powerup$ = "piercing" THEN
       LINE (bulletx, bullety - 10)-(bulletx - 2, bullety - 7), 3
       LINE (bulletx, bullety - 10)-(bulletx + 2, bullety - 7), 3
     END IF
     IF powerup$ = "shaky bullet" THEN
       CIRCLE (bulletx, bullety - 8), 2, 3
       CIRCLE (bulletx, bullety - 2), 2, 3
     END IF
END IF

Bomb, super bomb, piercing, and shaky bullets all have theire own look, as do the enemy bullets.
