The soundtrack is suitably bluegrass-inspired, with twanging guitar strings perfectly framing the swampy mystery. The voice acting too is pretty good, suiting each character to a tee.
Knee Deep doesn't look particularly great, with a cel-shaded art style, some slightly 'off' animation and odd-looking character models. Still, the visual style does lend itself well to the game's off-kilter atmosphere and storyline.
Aside from the straightforward puzzles, you can play almost all of Knee Deep with the controller on your lap as you make choices pressing one of three face buttons. It's nice and simple, enabling you to concentrate on making your choices and following the bizarre plot. Just sit back and enjoy the ride.
Comprising three acts, each roughly an hour apiece, you can polish Knee Deep off in about three hours or so. But then you can always go back and try mixing up your choices for different outcomes.
Knee Deep's achievements encourage you to play the game in a variety of different ways each time, posting purely one kind of report or responding in one particular way. It's not the way to play first time through, but then this is a list that encourages repeat visits to Cypress Knee.
