Open World Kirby is an incredibly cool thing. To be able to explore and unlock the massive world is super fun and satisfying. It's really rewarding to track down treasures, as well as warp rooms, new areas, and the bosses of each region. It also helps that the copy abilities in this game are really good. Stuff like Fighter, Rocket or Wheel are implemented really well, and then you got some out there stuff like Smash to find. They did an amazing job! <3
