More levels on this one now. I’m up to World (or Page, or whatever) 4, and it has got quite tricky. Some of the “targets” I have to achieve (such as “Get 45 Coins!” or “Destroy 15 Enemies!” are hard as it is too easy to mess them up and then you have to start over. Not only that, but some levels have dual targets – get 60 coins and finish in under 75 seconds, or whatever.
And Yoshi has turned into a boat a few times as well. For no real reason, except it provides a use for the tilt mechanism, I suppose.
