I recommend playing it (http://www.tastelikepizza.com/index.php?itemid=16163) with your sound on (no tricks). The simplicity of the game plus the soothing sounds/music it produces, and the tricky paths you have to discover make this a very mellow but somewhat addictive game. Got to level 20 before I became to drowsy lol.
There are only 2 rulez, don't hit the water, and end on a a single finish block (blocked with white and black).
You only need to use your arrow keys, and shift (to jump over a block).
Enjoy :)

Quite good, but sounds annoy after level 1
you have a very low treshold then lol.
