What's there to say, it's Katamari, it's super fun, right?

Well actually there's a bit to say. The gimmick levels are mostly better in this one though I strongly dislike the ones that are just "do X as fast as possible".
I also think the final level is much weaker and the soundtrack has less bangers.
The additonal Royal Reverie levels feel pretty pointless, they're mostly just levels from the game proper with some slight changes.

But yeah at the end of the day, it's Katamari, it's fun, go and roll some shit up.
