Overview: Get ready for a novel game experience as you tilt Yoshi through topsy-turvy worlds brimming with adventure! Yoshi can jump and stick out his tongue to eat fruit or enemies, but the main feature of the game is the tilt mechanism. By tilting your Game Boy Advance, you will tilt the world around Yoshi, knocking over enemies, swinging pendulums, and letting Yoshi run up walls and leap huge pits!
We'll be back with more details and the first screenshots once they become available (which I am willing to bet will be during E3 week). In the meantime, click here to get a closer look at the official box art.
