two things that really bugged me out. The boss thingy where the ship doesnt stop moving AND when the missiles focusing the new fishes, not the closest ones...
there could be more buildings to destroy, it was way too easy to end the game... the missions took way too much to be done... I ended the game with 15 missions done and as mayor...
Haven't heard this problem from anyone else. You could try to refresh the page, or maybe update your flash version.
