Oh my, such a lengthy thoughtful comment! I'll first thank you for playing the game and sharing your thoughts, and then try to organise my thoughts to avoid giving a chaotic answer defvgbfredfvg
I'm glad you appreciated the technical aspects of the game, I tried to put some thoughts to make it PC-like without making it too complicated haha, and I'm glad you enjoyed the art!
(Spoilers below starting now for anyone reading this)
Your analysis of the dynamic between the character is nothing short of excellent, that's exactly it: in the same vein as Matthieu from HSL, from whom Alois is inspired from, Alois isn't a demon, evil for the sake of being evil. But as Chloé's teacher, he refuses to see the consequences of his own actions (although Matthieu did see his actions were bad, while Alois doesn't). However, he's still causing objective harm to a person he groomed as a minor, and displays a manipulative attitude.
I wanted the ending to feel optimistic but, indeed, not idealistic: for example, if Jace doesn't call Alois a groomer, it's not only out of pity for him, but also because he doesn't fully realise it was grooming. To him, he's just cutting ties to a guy who's made him feel uncomfortable as he never respected his consent, and he finds weird that he got interested in him when he was fourteen. In my case, I only put the word "grooming" on this situation last year.
So, I agree, and the contrast with Kissing Snow-White, which you analysed, is interesting, because it was the point: all Jace's problems won't be solved thanks to a flower in his hair, but it can give him hope. I guess that is my answer to proshippers etc., claiming that the point of fiction is to create things beyond the realm of morality because it's just fiction and not real: I argue that, instead, fiction can reflect real experiences, and even a fairy tale can empower someone to open their eyes to the lack of respect of their boundaries. So I'd argue that fiction and creation in general are powerful, and it's what makes it beautiful, so it has to be handled with care and not support things like child grooming (such such being exemplified by proshipping for example dergvrf).
Also, thanks for sharing your experience, I always value this a lot and I'm glad you felt seen in Jace.
And geez, that's high praise to conclude! I'm happy you "enjoyed" it that much! Once again, thanks for sharing your thoughts, I cherish it a lot.
