Line Adventure
Its a twitchy arcade game thats something of a hybrid between the steering mechanic of slingshot racer and those rotating planet platformer games that are so darn popular,its also an addictive time-waster perfect for downtime at the office or the daily commute.
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.
