Simon Parkin Special: Gimme Friction Baby

It's one of what I call a Simon Parkin Special. Or, at least, I will now. Picked up from his flashgame-hungry twitter, it's Gimme Friction Baby. It's basically a cross between Puzzle Bobble, Bowls and those men who pay other people to inflate their testicles with saline. You fire balls upwards. Wherever they stop, they expand to fit the space. Each ball can take 3 hits. You get hits for destroying balls. You lose the game if a ball bounces back at you. It's pretty compulsive. It's a Simon Parkin Special!
