Hi-I just wanted to say that I really liked this game. I think (and this is a very wierd compliment) that you have a really good sense of pricing your games (I also played Devil and the Deep Blue Sea) and I think that for the amount of content both the games have, the price point was spot-on.
I personally didn't have trouble getting the endings, but I also used the guide for Charlotte/Sophia because I was doing them from a compleationist standpoint and not out of interest in their routes. It's not that I disliked the characters-I actually found their backstories interesting but I would have liked them better as friendship routes than romantic routes (but that is 100% based on my personal preference).
I did notice several typos in the game (or at least what I think are typos. I'm American so it could be American English grammer vs British English grammar happening)-I'm not sure if you're open to what I've noticed or what format you'd like feedback in (these forums, a new conversation thread, private email, etc).
***Spoilers Ahead***
My thoughts on the other rutes (I'm trying to keep this as spoiler-free as possible so some things are left a bit vague)-
I thought Bastien's route was OK. I liked him as a character but I'm just not (again, personally) all that enthuastic about the whole "overcoming class divide/inferority complex" dynamic.
I really liked the secret romance character but I just had a really hard time getting the implications of the romance out of my head, so I found it hard to get into (again, that's my issue not anything overtly wrong with the game).
I liked Leopold's route. I knew he was up to something, but I did not see what it actually was coming.
My favroite route was Guillaume. It was really refreshing to see a story where several of the interactions focus on a character's flaws or shortcomings and play through that dynamic. The one issue I had in that route was the denouement felt rushed. Specifically , in the last scene during the announcement it seemed like the MC was expecting what happened more than I (as the player) was. It felt almost like there (logically) should have been some sort of conversation/interaction between them that I somehow missed.
I agree with the other commenters who are interested in a sequel (or maybe just epilogues if a full-blown sequel is too much).
