Very solid entry, it improved a lot from the time I playtested.
I'm giving full points on sensory and metroidvania, as I think they're deserved. I especially loved the SFX at times, like in that one area with the plants growling before trying to eat you (magical biology).
I do have a few gripes and nitpicks. The first boss killing me in one shot actually made me explore everything thinking I was missing something, until I realized its unique weakness (not dealing contact damage), which made it go from basically impossible to beat to extremely cheesable. I feel like it might require some balancing.
Another thing is her hair power. That was often frustrating. I feel like the window to attach is small and picky, as I'd often miss the attach points while feeling like I had done everything write. Add to this inconsistency the fact you were usually punished with spikes for failing to attach and having to restart sometimes very far, it made the whole forest area a pretty frustrating experience. Gotta add that going downwards often meant going blind and risking to not catch any attach point. The trees don't actually give any clue on where the attach point could be, as it can be anywhere on the tree.
As closing thoughts, I think the weak points are around the execution and level design; the visuals, audio, atmosphere, and even little story, are amazing and I am giving full points where they're due.
