Bro, is it just me but some of them look like Sakura, Ino and Hinata?
I think it's the facial structure when you look at the girls from afar, as they're mostly flat upfront if there's no shadows (unless viewed from a different angle) and the complexion of their skin is similar to other Anime like Naruto. All the girls actually have the exact same skin complexion, I couldnt decide back then lmao since I was working everything (character design, story, angles, lightings, coding, scripts etc) at the same time, but I'll make changes in the future. Some of the girls are inspired by real people etc. Maze = Chaeryeong from Itzy.
