I like cutesy. Not that the games should always be this way but I really like the aesthetic and look of Lost World. Nothing wrong with a whole game being lighthearted now and then imo. Most Sonic characters are cute to begin with. In general I think the tone and aesthetic of the games should be portrayed seriously but certain things are just cute. Like in Mania Studiopolis and Mirage Saloon. The TV/Movie stuff, train/bar and the boss with with miniatures attacking you. That’s clearly all meant to be cute and fun. It depends when the cutesy parts take place. You can still have a mostly serious storyline as some games have already done. I think an element of cuteness has always been part of the Sonic universe. The Flicky animals, chaos and other various things.
