OK, I just played this for an hour and........... I don't like it.
Which is very difficult for me to say right now, because Katamari Damacy is one of my favorite games ever. Period.
Right now, I'm thinking that the only reason this game doesn't have explicit goals, is because if you DID have to accomplish something specific, you'd be so frustrated with the controls that you'd snap the controller in rage.
It's a diverting little sandbox, but as of right now, I don't see myself spending much more time on this title. Good thing it was only $5.
**All opinions subject to change. It took me awhile to get into Katamari, but once I did, there was no going back.
