Surprisingly calm, mostly because of the music, even though what you're doing can be scary. The art and music fit the content really well. The gameplay is solid, although I think the wind mechanic could use some balance as well as an audible wind sound when you are in those areas to give the player more feedback on what is happening. I didn't really notice the wavy lines until I flew off unexpectedly. Haha. Very polished and fun game!
