1 has a better menu system but I find 2 has more variety in their levels. When I'm not rolling anything in 2, I get annoyed by all the extra fluff.
Yeah, I hate the menu system in 2, it's retarded.
I haven't noticed much more variety in the levels, maybe because I only played 3 of them so far.
Update:
There's lots of variety in the levels now.
I hate the stupid fire level.
It's the only one in either of the games I had to replay.
I think I have yet to beat that level...keep trying too hard to get the katamari big and then I rush to finish and run out of flame.
The cloud one was fun, and the speedway.
The speedway is fun.
The cloud level is just weird... it's hard to tell what you can roll up. Like you get to a small cloud... and it's below you... wtf, can't get it till you're bigger.
You basically have to just charge the middle till you can pick up mid-sized clouds, then you're suddenly massive in zero time because most clouds are the same size.
Well beat everything.
Finding those blasted cousins was hard, especially on that raceway level.
I usually find them by accident. Think I have the speedway one
Pretty sure you don't. There's three.
