Not much progress since 2018, very slow updates, the guy aim at the perfection I think, but there's many much more games here to entertain you since an update.
Haven't played it since 0.1 but the first girl available at the time perfectly match the description of what you love.

I am not sure about the term "tsundere"? Starting cold and warming up over time? (Urban Dictionary) Romantically or by other means? By definition, would "Urban Dreams" count? I never heard the term before today, so sorry if I'm way off base.
