Nice..Fun..Simple
Very nice game.
Just one thing that kind of tweaked my bubble was that when you would move him side to side he would just stay in the same position, i know it would probably slow the game down of some sort by adding a quck animation for the left and right movement (but it's not a big problem)
Also i liked the way you could lower gravity and create a blast. But like someone before stated, it would be nice for the ball to become larger instead of having to look at the stars in the upper corner.
A thing that kind of made me laugh was when i died for the first time, the guy's dying voice. Kind of entertaining.
But yes, like many people have said, this is a fun game, and is a good tiem waster. You should make another if not just upgrade the game with the suggestions being given from other reviews.
Yet again, Nice Game :)
