Question regarding the last boss in Silksong

So here's the thing, Hollow Knigh is my favorite game but I was never actually good enough to beat the Radiance without some cheats/mods (let alone the Pantheons).

However, yesterday I beat Mother Silk after like 4/5 tries. Infact, it's probably the easiest boss in the entire game for me so far (with the exception, maybe, of the bell beast) so now I'm worried I'm missing something? I tried not to spoil myself but I did see there's an act 3 and I did the mission necessary to unlock it so what I want to know is, is this normal? Did I git gud?? Or is there a Radiance levels of pain boss at the end of Act 3?

Thanks!

PS: I did do almost everything I could in act 1 and 2. All bosses, all fleas, probably almost all hidden items, all quests, etc, etc
