Oh, man.
. Holy crap. Took me like 20 tries to 100% it, but god was that fun.
The level itself was pretty easy to complete. But god, those green stars and the stamp were pretty tough to grab.
In other news, I had a dream last night that I was playing Super Mario 3D World as a 10-year old boy. When I woke up, I realized that, this is the kind of Mario game I dreamed about playing as a kid. "In 20 years, Mario is going to be in 3D, and they'll have like 20 different power-ups and a million different kinds of levels -- and you can play with your friends without having to share the controller!" I think the only thing missing is Yoshi. Although I'm not obsessed with him like I was when I was 10, so I don't mind.
