The game is great. not SMB3 and Galaxy great. but it feel fresh and has a place in the top 3 of Mario great games.
It gets really hard... The music is very good for me. I liked the freshness in terms of powers-up possibilities.
I find it similar and yet different from 3D Land and coming after the gaalxy experience it didn't feel like a minor game at all. I didn't have the same (unfulfilling) feeling I had with SMWorld (after SMB3) or Sunshine (after Mario 64) if this make sense to you.
The graphics are great, the multiplayer is awesome; the only thing that could have made the best mario ever is the possibilities to fly and online.
Switch!!!
