Nice music and the intro was really charming. mainly really enjoyed improving my skills with the vine grapples since it was pretty hard to get a grasp of at first (mostly cause i was trying to get up at first using single vine).
i think the gravity being so strong is taking away from the core mechanic because you don't really have enough air time to make any mistakes and not plummet down. maybe apply the gravity exponentially so it starts out weak and eventually gets to the point it is now.
also i would add a bit more visual excitement to the main collectable
really solid game i had a great time
