I try out most all games that hit Xbox Live Arcade. Why not? They're free! These demos sell me on games. Occasionally I'll be surprised by one of the original titles -- Assault Heroes, for one. But none of the original content (including Geometry Wars) has been as enjoyable as my recent experiences with Switchball.

Switchball is a action/puzzler (one of my favorite genres) where you play as a marble rolling around solving physics-based puzzles through a variety of methods. Your can transform your marble into different types, such as a metal ball for moving heavy objects, an air ball to ride on fans, or a jumping ball for climbing stairs and boxes. You control the ball with the left stick and the camera with the right stick. You have to use the A button for actions like jumping or dashing, but very rarely. The controls are extremely smooth and the simplicity compliments the beautiful serene environments of the game. Even the bashing metal ball is still relatively peaceful. When I play the game I feel relaxed -- great for the Finals Blues.

Go checkout the Switchball demo on XBLA and let me know what you think.
