And now for Filler, a game so weirdly hypnotic that you half expect to wake up in a ditch with your wallet missing after you've finished playing it.

You play Filler by inflating balls, trying to cover at least two thirds of the playing area as you go. But your enemies are the bouncing balls, which can burst your Filler balls if they're still inflating. Filler starts off easy, gets harder very slowly and ends up impossible. But it's beautiful to play – like popping bubble wrap in reverse.
