I do like the Rewards, but I think there should be some more creative ones, like "Knock an enemy into 3 mines in one turn", "Have an enemy completely circle a planet, then burn in a sun", or "Kill 2 enemies from the blast of a dying enemy"

I suggest adding a variable called something like "isaBoss" and have the boss or miniboss come out only when it is 0, and change it to 1 when they spawn. This keeps 3 or 4 bosses from being on the screen at once. You will also need to change the explode function on the boss and miniboss script to set "isaBoss" back to 0 when they explode.
