If you liked Beautiful Katamari for the Xbox 360 you'll probably like this game. The main difference in this game is that you eat things rather than roll them up.

You compete with other dog looking creatures in the level to see who can eat the most. While I'm not a fan of Beautiful Katamari, it is fun for a while. So this game might be worthwhile.

And eating things sounds a lot more fun than rolling them up :P
