"Sludge" is a puzzle game for the Atari 8-bit computer which is
based vaguely on "Pipe Dreams."
A toxic sludge is being produced at the factory at a dangerous rate!
Never fear, you're here! Connect pipes to the sludge outlet to
control its flow. Higher levels require longer connections (and
more pipes to be connected.. for insurance reasons), and the sludge
starts flowing sooner.
(In other words, your hands'll be full pretty quickly!)
