14. Tiny, Huge Island
From this point on, I’d say there aren’t anymore “bad” levels in Super Mario 64, just some that are lacking inspiration, have poor level design, or just aren’t as good as the rest.
Tiny, Huge Island is a very cool idea on paper, harkening back to the iconic Super Mario 3 world, but it’s just not done all that well in Super Mario 64.
First off, it’s another mountain-looking level and there’s already too many of them in Super Mario 64 and Tiny, Huge Island is the least memorable of them all. It also just doesn’t really use the mechanic in creative enough ways; it feels tacked on rather than something you can experiment and have fun with.
Also, the windy area just makes the level a pain in the ass to get around and feels out place. Tiny, Huge Island is just kind of meh unfortunately.
