I never played the HD version myself, but I have played original 3DS version and I wasn't much of a fan of it. A watered-down sequel with a disappointing cast of ghosts and a tacked-on mission structure, with its difficulty level making the Kirby franchise look like Crash Bandicoot (especially the upgrade system).
Not a bad game, but after having played the predecessor on GameCube, I was disappointed.
