Looking good, wow!
Art crits:
-- The bright saturated colours in the background + the bright saturated colours of the player character means she doesn't stand out much. Especially without some kind of outline. While the unified look is nice there's the issue of everything blending together visually.
-- The direction arrows in the tutorial levels could look so much nicer! Are they placeholders right now? I was thinking more that the word was integrated into the cloud, rather than the the arrows being clouds with words written on there. (other than that I love the style of the sun and clouds though. More than everything else, haha)

Gameplay crits:
The player character feels very slow and floaty? Probably because her fall speed is quite slow. It made the boss fight annoying rather than difficult. It'd be nice to get an option to drop faster (down arrow?). She doesn't feel swift and agile which I suspect is what you want with the "cutting wind" theme.
