It's cute, fun, and meaningless. Interesting how we got such a fun movement mechanic so early and how little reciprocity it received since then. This is purely based on established aesthetics, because few people will object to that swinging at high speed with a nice rhythm through a sun-drenched evening sky between floating islands just looks good. Beyond that? You'll see very little. This is more of an escapism game than anything else, and if it was released today it would be a different story. But it was pretty early and built a nice bridge between minimalism and accessibility.
