My man, we have the same taste. Have you found any similar games with reasonable proportions? Asking for myself
Goddesses Whim (one of my favs), Dissonance, and Winds of the Destiny have some great ones. Scarlet Law has a few good ones, as does A House in the Rift, Adventurer Trainer (If you like Konosuba and Re:Zero), Ripples, Afterlife Harem, School of Love: Clubs, and Halfway House. Unfortunately for these and the other big eroge out there, they usually have characters of all types to service all wants, but favor bigger proportions in general. These are just ones that I remember having more petite girls or have reasonably believable proportions in comparison.
