Plus, the Smash Ability didn't have an Inhale like in the Amazing Mirror.
Huh? You couldn't inhale as Smash Kirby in Amazing Mirror, nor could you do anything similar like grabbing enemies. Smash in Dream Collection is a pretty faithful recreation of the original version in Amazing Mirror, with multiple Stone forms. It actually has a new move though, which took me a bit to notice. It's a dash attack that's like a shorter version of Fighter's longer dash move, although you can charge it to go further.
I really enjoyed the Smash Ex challenge because of how versatile the ability is. The mini-boss rush feels like a worthy challenge for the ability.
