To me, this just seems like a less visually and aurally pleasing version of Katamari Damacy. However, If I hadn't played katamari prior to this game, I would probably love it. The king and his tight pants just overshadow anything even vaguely similar.
I loved it! The colors and concept are beautiful! But I agree with mimosalotus, having the big fish in aquarium mode was really stupid. I wanted to admire the artwork, not have to click the mouse 500 times in the process just to get those fish of the screen. Other than that 5/5 FAVORITE!
