Luckily thanks to the restart taking you to the beginning of each level I was able to complete the game. I found many times I just dodged the ships and I won. The last few levels were pretty challenging so that is good. The game also has music (although short). I do agree with KaisarDragon though. A couple of spelling issues in the tutorial screen (I just hate to see those). And some minor things: the bullet disappears when you die and when you revive, the ship can immediately be hit (this is bad on the last boss). Pretty good game.
