So your question was actually about the controls? Sorry, it wasn't clear.
You can use Touch.SpeedAt and Touch.AngleAt expressions to detect swipes on touch screen. For example, if Touch.SpeedAt(0)>200 and Touch.AngleAt(0) is between -30 and 30 degrees, this is a swipe to the right.
There are quite a few tutorials, but they all are giving me "500 exception" error at the moment, must be some temporary issue, try opening them later:
