Well that was dull.
What you have here is a classic example of a good idea being ruined by just plain animating/ scripting whatever. There is no point in making one ship the size of half the screen and the other the size of a hundreth of the screen, make them all the same. Make a afun game. Thats pretty simple to do, before you submit things like this test it out and ask yourself "is this fun? What can I add to make this better?" And things like this. I personally hope you remake this into somthing better. Anyway poor game to be quite honest try better next time.
