Nice entertaining game, but still remains only a classic genre of game. The graphics were pretty nice and so was the level design. Just two things I would recommend are that in the introduction, you make the guy's voice a little bit louder, because the music would overlap his voice sometimes, and that you add a stat to show how much rocket you need to shoot to get the gold medal. If you keep those in mind you'll get a perfect game ;D
Overall you did a good job here. Keep going and you'll eventually get places :D
Cheers
