look buddy,
this game, as is, is a complete waste of the player's time.
without addressing the following points your game will never be popular or even worthy of anyone's time.
1. Change the appearance of the ship. (its just two simple shapes put together)
2. Make the enemies shoot back.
3. Make different types not just bombs.
4.More realistic physics of flight.
5. Gore
Right now, this game sucks. The next time you submit this without changing it, i guarantee you that someone will be very unhappy.
