Playable...
The game was good and pleasing to the eyes... and a little addictive too... (damn I couldn't get the last star)...
Anyway, the bad point of this flash was that it was repetitive... and so... quite predictable... you could have had the ball come out from other points....
And as someone has said before (v), the game presentation while being good was clearly aimed for a younger demographic...
While the concept itself can be made into a game suitable for slightly older demographic, you will need to update the interface to not look this childish... (not saying it was bad... I kind of liked the cuteness of it... :-p)
And a soft bgm would have been appreciated...
