Back in early high school whenever I had an intro to technology, business, careers, etc. bird course in a lab, I wasted so much of my class time playing this.
I've actually gotten to the fourth level (it goes psycho slime then a black one iirc) playing normally, but only once or twice. There's actually exploits for each level which only involve hitting the ball two or three times at specific spots. The exploits, once my friends found a tutorial flash demonstrating them, really ruined the game
tl;dr: huggle please
