**Spoilers ahead too**
Thank you for writing this wall of text because I LOVE detailed reviews. Especially since you covered all characters. Sorry for the late reply, because I wanted to write something decent.
It heard many people had upcoming exams during the release. I didn't intend to mess up their priorities and sleeping schedules. Halloween seemed the perfect holiday to match the game's theme. I just pray the game was all worth it.
You're a master of speed gaming to play all routes in one go. Were you lucky to get all choices right or did you scroll back for the pings?
I totally get what you mean with repetition in routes. It makes other routes not as exiting as the first playthrough. I played around with plot structure, choice system, art style and character involvement. Each route has their own outstanding style. Now you played all routes, you can sort of combine the puzzle pieces. The characters have their own way of describing events. Regardless, what happened stays the same.
I treasure each of my OCs and wish to show more of them. Their stories may not be as fleshed out, but enough to spark interest. Adding up, the MC's choices influences their paths as well.
When you replay the routes, you'll pick up all hints dropped earlier. Even the play order drops clues. Like you mentioned, Zeikun > Sachiro. The little boy was the least liked for his appearance, but more people started to like him in the full version. Depending on the ending, his route is split in half of the time looking young and second half being older.
Zeikun has been memed as model for L'Oréal Paris shampoo lol. My love for drawing long hair is obvious at this point haha.
Kurato looks like easy going, yet his route is slow burn. All side characters appeared there and he had to deal with all of them. The affection points makes a difference in the endings that even the side characters act nicer, heh.
Junoru has this sad look glued on his face so I give players what they expect but it's a surprise it seems. He has been lonely for a long time and enjoys company. Like in his first chapter he has the most conversations with the MC. People have "complained" to me why I killed off all handsome characters lol. Initially I didn't want to give Junoru's parents a face, but then thought "it makes the events sadder, right?"
As for the other side characters, they contribute each their part in the routes. Some are to like, others to dislike. I wanted to show more of their sides. Depending on your choices, you can find out more about their intentions.
Anyways, thank you again for this feedback!
