Holy peak lyrics batman! In particular, I love that in the boss fight, the miniboss fairy comes back in just as the song is switching over from feeling ill from poisonous mushrooms into (the elf, or the fairy?) gambling her soul to have her feelings reciprocated!
Both songs end up tying well into each other. I love that you get the sense the fairy is more contemplative, and wants to express her feelings and thinking of the past/history of the forest made from love. Meanwhile the elf is more concerned on the moment, making sure her metaphysical forest isn't torn down by pyromaniac cats and poisonous mushrooms, starting her song talking about herself, concerning herself of her future just as she's writhing on her deathbed.
Both characters are hurt by the forest, the fairy just by navigating her way through it, scraping against it's surfaces, ready to let dangerous cats go through as she mourns through her feelings, and the elf by thoughtlessly consuming within it, consuming too much poison, unaware of the fairy's advances. One ignores the world, and the other ignores her heart. Or maybe I'm looking into that backwards I'm not sure.
Always like when fire has a "lifting" property to it, always makes it feel a bit more real. The boss felt really well designed around that mechanic, having to rise the fire into the boss while being wary it doesn't rise yourself into a bullet, or making sure to lift yourself over sweeping waves of them! Great use of fire overall as a platforming mechanic, with wings to be used as a lifeline of sorts. Cool game!
Also, just now got the ending where you don't lower Sylvie's health bar fully. lol.
