This is a very lovely game so far. The art style is a wonderful painted style that approaches realism, and I especially love all the different poses of the NPCs and their vivid facial expressions. The many, many CGs are a treat as well, like a picture book. The backgrounds are well done and are in the same art style as everything else (points given for that). The love interests are charming, each in their own way.
The writing is engaging and crisp. It does a good job of establishing the world that these characters live in. As for the story, consider me hooked! I love the mythology that you've established, and I can't wait to find out how it develops.
[SPOILERS AHEAD]
And now I will theorize and share my thoughts on the story!!
As far as I can tell, there are two factions. The Royal Council of Wizards and the sorcerers, and then the other "secular" factions--the Kingdom of Cirelon, etc.
Lindinis was perhaps a town of sorcerers, and was burned down/destroyed by the Council or the Council's followers. Silvana either had her memories removed by the Council or lost them and the Council decided to take advantage of this fact to observe a sorcerer in their natural habitat or use Silvana as a weapon against the other sorcerers. That year Silvana spent in the house was meant as a trial period almost, to see if Silvana was "safe" or if she would regain her memories. Personally, I think that a war is coming between the sorcerers and the Council (and Council-adjacent allies), and the Council is hoping to use Silvana in this war, which is why they let her attend the school. (Matthias also said them letting her go was an "investment")
History is written by the winners of course, and there were a few allusions to this in Silvana's conversations with Chloe. It is possible that the sorcerers are "innocent" and are being unjustly persecuted by the Council for whatever reason. Alternatively, the sorcerers may be just as terrible as described, and the Council is justified in outlawing them. Of course, the truth may be somewhere in the middle, too!
And those are the thoughts I have so far, my little theories on how the story will develop.
There are games that I hope to come across when I trawl through itch.io's long long list of visual novels, and this is a great example of it. A game that is a representation of one person's vision. I find these kinds of games to be great reads.
But at any rate, keep up the good work, at your own pace of course. I'll be eagerly awaiting whatever you have next. :)
