Just a very fun gameplay loop. Very easy but the real challenge comes from pushing yourself to create the perfect route and make a perfect Katamari. One of the most satisfying endings I've played through and has a great soundtrack. My biggest issue was with the "collect one of" missions just because I'd roll this massive Katamari and then get blasted by something and roll into a tiny object with no option to retry immediately. Just gave up on those levels entirely tbh. Loved it though
