Need improvement
It is not a bad game, but there are my views on it:
Gameplay:
It works, but it is way too easy and slow. Infact, I see no way how you can lose, when you try atleast a bit. It would be better if the game become faster and faster or when the amount of red platforms increases. Maybe you could implent different difficulties, so that it appeals to different players. Still, too easy at the moment. Also some kind of highscore would be a nice touch.
Graphics:
They are somewhat decent, the ball and the platforms look nice and so does the menu. I am indifferent about the background, it looks a little bit too plain to me.
Sound/Music:
Well, the sounds are okay, but I think that the game would profit a lot from a fast paced background music. The lack of said music made the game boring pretty quickly.
Recommendations:
Make the game more difficult, add possibly different difficulties, adding highscores is optional, a nicer background and good backgroudn music is all that this game needs to be a good time waster.
