@BlueScope, that time I hadn't updated. but right now I upload the it, and it was very good, here are the updates that I made:
1 - now you can shoot the two shots at the same time.
2 - improvements in the ship sprites.
3 - Icon and sound alert when the ships are coming behind you.
4 - fixed the bug that sometimes while creating some immortal enemies.
5 - adjusted the volume of the sounds of explosion and impact.
6 - I changed the button "Play again?" to just one phrase "Play Again?"
phew, that's all :D
