For what it's worth, I actually enjoyed this game a lot. I thought it was extremely creative, and for god's sake, the Princess of the Mushroom Kingdom hasn't had her own solo game since the DS era. I hope this does well enough to span a side series of Peach games. Not only are they the perfect amount of satisfying, but we also get to see more of the Princess herself; not just as the damsel in distress. My ONLY gripe with this game is that it's a completionist's nightmare. There should be a way to either backtrack during the level to find hidden sparkle gems (which in of itself is satisfying), OR once you complete the level, if you were to go back in, you can start from a different area. There's no need to do the entire level again, I think that's just extremely obnoxious.
My favorite costumes were Figure Skater Peach, Mighty Peach, and Swordfighter Peach! I'm super glad I played this.
