Circus is a text adventure game for the ZX Spectrum that was published by Digital Fantasia as part of their Mysterious Adventures series. The game starts out with you stranded in the middle of nowhere, your car having run out of fuel. You walk down the road looking for help until you find a big, active circus. This circus isn't all that it seems at the surface, however.
CloakTheLurker for this run takes a crack at this game and blows up the circus in record time.
