There's a handful of really great levels in Yoshi's Woolly World, which makes the most of its setting and choice of character. The world is exactly what I expected, thematically and in terms of structure: sand, snow, clouds, and fire, punctuated by bosses holed-up in themed fortresses.
Arts-and-crafts style; Imaginative; Yoshi's challenged
Only a few great levels; Tedious boss battles
