I like a lot of the new features. I was perhaps hoping for even more features, like more bosses, custom music, more powerups, new themes, but what they've shown is cool. The only thing I'm really don't like are the upside down levels. I don't ever want to play a level that is upside down.
I'm a bit worried about other features though. Having to pay a online fee to just download/upload levels makes me partly want to skip the game. And having to pay a fee and connect online to play local wireless is awful. There's also no local play on top of that?
The game is missing features like 100 mario, costumes? I don't mind trying out endless mode, but why take away 100 mario challenge? Can we play it online with friends or not? How does things like tags, level search, level sharing outside of the game, endles mode work exactly?
This direct answered a many questions but also created a lot of new ones. I think they should have made it more clear in the direct about what the game has or don't have instead of showing a 5 minute tutorial. There shouldn't be this many questions this close to release.
