I definitely prefer the more open-ended 3D Mario games but despite the linear gameplay there are some really great levels here with some solid mechanics. Being Cat Mario and climbing around is really fun, and the Double Cherry is so much fun as a power-up. It is a little disappointing that most of the worlds have no consistent theming outside the world map, as it kind of takes you out of the immersion. The final battle with Meowser is fantastic, however, with a phenomenal atmosphere. The post-game also has some really great levels that ramp up the difficulty significantly.
