I think this game was widely misunderstood.
I can't rate it as a 5-star otome simply because of two routes that weren't as well-written as the remaining.
This game portrayed some disfunctional relationships and tried to teach readers how to speak up for their own needs to improve the relationship, which is something most otome games don't do. Some routes were basically about this. I really loved this about the game. Indeed, Amnesia had other flaws, but darn, in certain aspects it was way ahead of its time and the writing still feels pleasant to these days.

Also, the art direction is superb. I enjoyed the most its soundtrack, though. I've yet to find another otome game with such a superb ost.

If you speak Italian, I wrote more about the game on my blog :) You can read about it here: https://diveintofantasea.wordpress.com/2024/05/18/lamore-attraverso-i-ricordi-perduti-amnesia-memories/
