I don't know why but I had this bias of thinking Kirby games were all good but were all kinda the same too. In fact I don't remember much of the last game in the series: Star Allies.
But this one was actually really good, very fun, memorable ! It was like I was playing Kirby for the first time again.
3D doesn't add much imo, but they transcribed the classic kirby game-design in 3D really well.
Nice subtle lore, very cool postgame !
