Great game, one MAJOR flaw though
the game is a good game overall, it is quite challenging, which is good, but PLEASE make a check point or continue or even a password system to allow the players to jump back to the level they died on instead of going through the whole (not to mention long) game. for instance, i got to level 3 (where you defend against ships) i made a slight mistake and died, then i have to replay pretty much the whole game again. i love the way you turn a def game to an shooting game.......creative thinking
