I can't express how much i enjoyed the game. I discovered it from the link you published on deight class server. And from what i have seen, you truly hold the standard brought by Lucy on terms of WG VN.
Your game has many qualities but i must put the emphasis on the efforts put on the production : the visuals, the transitions, the musics... It does not feel sluggish nor too harsch. And i think this is the most polished and smooth WG VN i have seen in terms of pure "game".
Now, i find the rythm very good. You have a good writing, sometimes funny, and always impactful. And when you say you plan on adding some gamyfying features and point and click mechanics, you find me doubtful.
I'm not saying it will be bad and you can not do it. I'm saying other games of the same genre integrated it. And it felt like feeling a pie with dough. You have more to eat, it does not taste bad, but it spoils the fruits.
Anyway, i wish you the best. and congrats for Lunarnalia.
