I stated this on the quick look and I'll say it again here: as a big fan of Yoshi's Island I HIGHLY recommend you change the controls to the "B" settings and the "Hasty" egg throwing. This makes it play much, much more smoothly.
Why is this $50 damn dollars. That seems like a lot. But boy do I want to play this .... must resist.
These Atlas games have a wonderful way of being $50 up front and then getting dirt cheap within a matter of months. Just look at the price of SMT4 or Persona Q or other related games on the 3DS. They started at $50 and are now very regularly $20 or less.
