I think that this game isn't very good. There is one good thing about it though, which is it's gameplay which is good, and classic, but everything else is bad. For one thing, the music sucks, you posted something from a tutorial, no replay value, no effort, no story or anything to make it unique, it's way too short, and it looks like you only worked on it for five minutes. Please try harder next time, and please make a game that is actually worth playing.

cool

Not bad, but needs improvements:
#The graphics are simple and plain, maybe a rotating effect on the ball and a shinny effects in the coins may change the game feeling into more complex graphics.
# The song end in somepoint, is not a loop that has no ending. Also there is a bug when you die the music of your previous life don't end and keeps playing while the music when you press "Play Again?" begin, that's very annoying.
#The difficulty is ok for the three first levels, you need to add more levels and maybe new gameplay elements.

Very fun indeed. Love these types of classic platformers. Never gets old.
