Can this be...the end?

After fifteen fun-filled levels, it's all over. There wasn't even an interactive credits sequence. I'm left hanging.

What's that? You detected Super Mario 3D World save data? Alright then. I'll be off to explore some bonus levels.

Since Captain Toad can't jump, how is he going to smash floating blocks? Oh. Looks like I have to smash them for him.

Favourite of the first 18 levels:

Boo Mansion - probably because there's a lot of rotation involved.

Blizzard Express is a very close second because it's reminiscent of the Bowser Express levels on Super Mario 3D World.
