Not Bad for your first!
I actually found myself enjoying the game, for the first 50 points :-P I was hoping something new would come across. I think this game has potential to be something good. You could add a new level every 10 points rather then just increasing the rank. New obstacles would be nice. Perhaps some moving "bad guys" that keep you from getting the coins. Also, I liked the Jazzy music. Hope you make another one!
