it's hard to put it into a genre. it does have elements of puzzle games but it's mostly a chill game where you roll shit up and get bigger and roll up bigger shit. there's different challenges like you get shooting stars if you do it fast enough, the king praises you if you get it big enough, there's presents hidden around here and there that give you cosmetic items, etc. some levels have specific goals like roll up all the fish, the only ones that piss me off are the bear and cow missions where it ends as soon as you roll up a single bear / cow and you want to get as big as possible to roll up the biggest bear / cow in the level, once you get proper large it's hard to even see the tiniest bears / cows and you have to kind of memorize where they are and some will move around the map, those can kiss my ass. the rest of the game is unique and fantastic.
