Game Stitch Podcast "One More Line is viciousness without respite. A hardcore gaming experience" PocketGamer "An addictive time-waster perfect for downtime at the office or the daily commute" Techly.com "It's a twitchy arcade game that's something of a hybrid between the steering mechanic of slingshot racer and those rotating planet platformer games that are so darn popular." Toucharcade.com "SMG has got the formula precisely right. It's a fast, eye-catching game that's mechanically difficult, but the controls are simple and intuitive, so you never feel cheated, only beaten by your inability." ABC.net.au "An addictive and challenging yet deceptively simple arcade game" Jay is Games "One More Line is most entertaining single button game that I’ve encountered." superatomica.com "The controls are responsive and accurate, and if you have a good self-control, as well as a propensity for the psychedelic seventies, this could be the right game for you. 8/10" IGN Italia ---------------------------------------------------------------------------- Original music by Sydney composer Batterie: Listen / Buy here: http://batterie.com.au/listen/
