Circulate is a physics puzzle game from Pi Eye Games, creator of System Mania and the far-too-cute Kitten Sanctuary. This simple title is built around moving marbles through a circular container so they disappear, whether that be through forming matches, falling into black holes, or even smacking into bombs.
System Mania is an arcade game that borrows liberally from the ever-popular resource management genre. Instead of serving food to customers, however, you spend your time fixing their strange contraptions by turning off warning lights as they appear. The fate of Fiona's growing fix-it shop is in your fast-clicking fingertips, so pull levers, spin wheels, and flip switches as quickly as possible.
