It has a fun little personality but it's one of the more underwhelming new tracks imo.
Also something that's bugging me about this is that Rosalina seems to be the one advertising it. I really don't know why. It doesn't seem to have any connection to her. Visually, the track looks okay at best. I would've preferred her to advertise something more fitting e.g. something from Super Mario Galaxy or even her Observatory. I really don't know why they aren't making tracks of some of the best looking locations. Heck, even Super Mario Sunshine got a track.
