I started Rhythm Paradise Groove today. I reached Remix 3.
It's as fun as always. Minigames are crazy and charming and the music is great. Rhythm Paradise is the series that sticks to Nintendo's "putting smiles on people's faces" motto the most, and Groove definitely delivers.
However, I can't help but notice how the menus and UI look very sterile and bland compared to previous entries in the series. It's not a big deal, but I wish they worked a bit harder on it. Also, unlike in previous entries, Remixes so far don't have any unique visual themes and are just a collection of minigames. This actually bothers me quite a bit because Remixes are usually the high points of Rhythm Paradise and at least from what I could play, this is not the case anymore. I hope this changes as the game progresses...
