I've just finished the 0.55 version and I felt like leaving some comments.
As a computer engineer who has been willing to specialize in artificial intelligence, your work was really gripping to me. I was immersed and hooked to it. I couldn't relate more to the MC and the story.
Your story hits the spot. I have a thing for goddess characters and, just like you, I enjoy powerful girls. You wrote a mind blowing story that contains my greatest tastes for fiction: AI or stuff that involve futuristic or advanced technology and supernatural (the supernatural world, goddess and angels). Also, you even mix magic in it.
I also could relate to the MC, not because he might be a computer engineer or AI specialist as well, but because of his personality. My personality is not that extreme cold like his, but he does have many features that I have. I think that your character development was decent in general.
I confess that the prologue (or just the non-sandbox part) got me rather emotional, feeling like about to cry. I have never felt like this while playing any game before (I said any game, and not any VN!). I found your story so sad! I won't elaborate more on it because it could leak spoilers, but while I was processing all the current situation and everything that had been happening in the plot, I found it was too much sad!
I didn't like that it had been turned into a sandbox game. I know that you had your reasons for doing that, but I still don't see the need of it. Also, I think that a sandbox game is more laborious to you than non-sandbox.
I also see that you are building up some harem here... I wonder if Aisha would be okay with that.
About the girls, they are all stunning. They are all attractive. Beira and Hilirika are my favorites. The appearance you provided them is on point. But... Dude... You really are addicted to writing sad stories, aren't you? So is Yukinari going to pass away? We won't meet her again? Not even the child will be presented? I don't want to believe that you introduced her in the story just to kill her that easily... She is a nice girl and I have already created emotional ties with her (but the MC isn't like that, I know). I wish to spend longer time together with her in the future. About Beira, I disagree to the way she was treated. Her story is also a bit sad and I also hope to spend longer time together with her, putting a smile on her face.
Ai is a sensational character. Her powers and lines translate much of the creativity you have. I would never imagine something like that, reaching a godlike level like she reached. It is satisfactory to know that such powerful and close character is always together with me. It feels... Comfortable, if it is the right word to describe it. Ai is a wonderful idea.
Your game is impressive and I had fun. I want to play the future updates and follow this game until it is finished, and I might also follow your future new projects. However, I have read some of your posts and you seem to be unmotivated to keep updating this game. That's sad and there is nothing I can do about it. I hope that you won't call it off and will finish this game, I really want to see the end of this story. You are a good writer and the universe you created is entertaining to be immersed in. Thank you for developing this.
