The puzzle like elements displayed in these levels are not that common in the series, there's great potential with this game to create a more "brain" dependant type of progression. In that sense this could bring something new to the series.
The alternate routes implemented in the levels where simply incredible.
I kind of wish they waited to release this until their next device, would prefer to have it on a sleek handheld.
With the new universal and homogeneous design philosophy at Nintendo we shouldn't be surprised if this game was easy to convert to otther platforms. So why wait more to play it?
Still not sure how I feel about this.
It kind of feels like something that would have been more timely on the SNES around the Mario Paint era.
What about things like easy global online level sharing or the fact that it uses one of the strong perks of the touch screen which is content creation? Not to mention there will be an important level filtering with the ranking systems, something like that would have been a lot harder to implement in the SNES days.
Talking about the impact on future 2D Mario titles and their sales, that can easily be countered by Nintendo with the inclusion of new ginmicks in the following games and of course multiplayer which this game lacks.
