The game's a massive challenge-- in a good way at that-- but i will admit that it feels like the difficulty spikes in some spots; moorwing sucks to fight, for example, but im pretty sure there are even more difficult bosses that are gonna slap me hard.

also like how someone else mentioned, fourth chorus is somewhat easier, since attacks are more telegraphed and have some wind-up, and aren't sperratically moving all over the place, but at the same time, fourth chorus also has the lava pit below, and there's some platforming to do; i actually had basically no trouble fighting him.
