My flash game

Hi my flash game is at:

the one im having problems with is spaceship, and was wonder if someone could download the fla and take a look at it, the only thing i was curious about was how to make a mc explosion for an enemy ship, show up where a different mc(the enemy’s movement, not scripted). some of the enemy’s explosion works because the mc’s path is scripted and not drawn. so mainly just look at each level and tell me how to make to explosion show up where the enemy got shot.
