I found about this game looking at the latest updates and just played it.
The first impression is great. The characters look nice and original. The story starts fine I guess and the history behind it is very interesting and makes me want to learn more about it.
For the technical part I'm bluffed by the originality of the models. So many games have plain skin that doesn't look human at all and that ruins everything. This is just fine here. I was particularly pleased with how you took care of the mother. She actually looks older without being less beautiful. Your work on the skin is one of the best I've seen around. The only thing that I find a bit overdone is the thigh gap of the two girls. They don't look anorexic to me so aren't they supposed to have a bit more flesh on the legs ?
I know that the modeling issues that I mentioned in the spoiler may be tricky at best, but it's just my contribution to attempt to help make the models more anatomically correct. Of course if those design are intended please say so and I'll keep quiet about that. I'm not nagging or anything, just trying to fully explain my thoughts and comments.
I also hope that you can find someone to proofread a bit more the texts. I'm not a native english-speaking person myself and not reading the text out loud makes the (few) texts with mistakes a bit difficult to read and I loose the immersion into the story.
Even with it's little youth flaws, I find this game one of the best around so please keep it up.
