Needs a way to block out pixels we know are grey, or have an all white grid and let us place the two colors. Also let us look at the picture at the end of the puzzle. I have completed 6 or 7, but there's only one that I know what the picture was (a circle).
I had the same problem of a game over with 10 sec. left with the fast game and the score pop-up is not a problem in the slow, but in the fast game it gets in the way.
To all those saying that the guns is not firing fast enough, let your small ships take care of them and concentrate your big gun on the bigger ennemy ships
