Sometimes it's nice to sit back and enjoy a simple game that just feels good to play. Cado by Clearcut games have taken the sketchbook motif that was insanely popular amongst iPhone games a couple years ago and have used it to make a well handled physics action game.

Cado, a black ball needs to get to the portal in each stage. The way he travels there is through rotating the level left or right, causing him to roll around the various obstacles into safety. There is also a star to collect if you're feeling amorous. What makes this simple concept shine is the attention to detail the developers have dedicated to the way Cado travels along surfaces. Rotating too fast will fling you off the platforms into space and to travel around some of the objects requires a precision of balancing your rotation controls that feels near perfect. In later levels spikes are introduced (cause hey, you have to have spikes), and some shapes are quite difficult to navigate.

As mentioned, the game uses the old sketchbook aesthetic we've seen a thousand times on the iPhone. The blue lined paper background and the sketchy objects still work however, evoking fun and nostalgia from school days past. The music is a single catchy little track and is quite suitable for play, but does wear out its welcome after a while. The forty levels on offer seem to blitz by all too quickly, but more content is promised in the near future.

What we have here with Cado is bare bones gaming. No fancy visuals, no intricate level design, no complex game mechanics. What you do have are fantastic controls and a lot of fun. Especially at its low price, Cado is worth a look.
