Well, I finished the game. I like your project, althoug it has some issues. I´m giving some feedback if I can help you to improve it.
1) Ok, I love Microphone animations and its comic behaviour; also the Mr. Ball response hehe. But the dialogue scenes are very long. Try to combine two sentences in one box for make them shorter. Repeat, I think the best part is how you put some charism into "Microphone" character.
2) The movements of the player are very smooth, instructions are clear and it´s fun to play with. It´s short and easy to play.
3) The camera is shaking all the time. There´s something in the programation that make the camera moving to one point to another. It makes it a little painful to play. The background... Abuf, it´s also difficulting a lot to playing well.
4) Music is repetitive an bad. The sound of the ball is looping, maybe?
5) There´s some bugs at the begining maybe? The ball transforms into a pink box hehe. Some gray transition... And the scare screen doesn´t work, sorry ^^!
But, I get a great time playing your game (twice!) to the end, and it as funny. ^^!
