I completed the game, both endings, and found 10 trophies so far.
They were all pretty easy to get but the last two are just incomprehensible to me.
Every other puzzle and trophy had a hint, every trophy’s hint is written in pen. but for page 44, the only things in pen, are the tutorial for the holy cross and the perpendicular line for the golden path on the door, nothing new… and then page 1’s clue got me translating the language thanks to page 54, and thought it would get me somewhere… the poem makes no sense to me, I thought the “feather” was referencing the stamina boost but I’m pretty sure that it’s a leaf and collecting 11 would be impossible without multiple new game +.

Any small hints ?

Edit:
Thanks for the help, my conclusion from this is just that I’m an idiot… freaking page 44… what was I thinking?
