Quite good! I like the variety of mechanics and the pacing, even though the core system is very simple. I would, however recommend:
1) Add a visual indicator for the wind at ~700m. Wind is already a somewhat frustrating mechanic in most platformers, and while it is a fine addition here, the lack of indication as to its changing direction and magnitude isn't adding anything in my opinion.
2) Add a bit more of an indication at the beginning as to how we ought to start the climb-- I missed the platform on top of the shop because I didn't realize only the right half was solid and spent a few minutes looking for another way up before I realized my error.
