This game is their second best game?
And Salvation is their first?
Civilian Justice League 2 had a public reputation system and impregnation mechanics.
Liz & Tower Town had publicly random sex encounters with significantly more events than any other game plus a unique item gathering/crafting system.
Hypnosis Aristocrat allowed you to mind control adventurers or go out and be one yourself as you slowly strengthen your mind control powers and eventually make yourself the ruler of the town you live in.
If we count Salvation as the top, that makes Detective Girl their 5th best game bro. Unless you think Detective Girl somehow beats ALL of these games, even though it lacks features they all had.
Detective Girl has no impregnation, no item gathering/crafting to raise public affinity, no mind control mechanics leading to literally usurping your uncle as Town Noble.
All Detective Girl has is a tomboy protagonist.
