Great game!!! You actually balanced the speed and shots size depending on your scale, not too many people did that and usually in other games it's better to just stay big all the time, but your game is not the case, you did a great job! Also, I guess that the score that you obtain come from the aliens and not from the meteors, I was constantly finding meteors but I couldn't find too many aliens. Except for that little detail, the game is really great!! :)
