I would say it's about the same length of the other Nintendo Platformers so maybe around 20-30 hours for 100% ? Kirby games have a really satistfying feel to them and suddenly you arrive at the last 2 worlds and you get some pretty nice difficulty. I gotta say, Kirby games have one of the best bosses for a 2D platformer. The final bosses never disappoints.

Yeah, I could tell after seeing that boss battle clip with MetaKnight(is this correct?), and about the bosses, are they all hard or at least at normal difficulty? Cause Whispy Woods was too easy, yeah I know it's just the tutorial part, but I hope bosses aren't too easy though, felt like I didn't do much(or anything at all) especially with a full team.

Wispy is never hard :P

They ramp up in dificulty.  They're never really, really hard but they can give a nice challenge later in the game.  Main thing is they are fun to fight, not just an uninteresting enemy with an obnoxiously long health bar.  And the final bosses usually pull a crazy twist out of their hat.  

Having said that, having 4 team members is going to reduce the challenge, obviously.
