Shift - a cool free game for Windows Mobile

So here's another addictive game I just found (and tested in some meetings I'm attending these days...)
As usual, when I recommend on a freeware I try to focus not only on the functionality but also how it looks from user interface standpoint and how simple it is to operate.
In this case, I must admit that this game is close to perfection!
The game is enjoying and not long, the user interface is beautiful and above all - very very simple and intuitive. There' a lot of things to learn from this game about how to design one for windows mobile.

My only problem right now is that I am making more points out of accidental steps than out of the my planned steps...
The game can be downloaded fro free in many sites, I found it in here.
