I noticed it right away. More people need to give the game a chance. It's a LOT of fun and it's honestly in the running for the most gorgeous game on Wii U currently, imo. Definitely a noticeable step up from 3D World, especially in the lighting, but also in some of the textures, which you can see in detail thanks to the camera zoom in Captain Toad.
