a question. Because they consider only ten episodes when it's a pretty good and entertaining game.
Many developers but almost all, end the games practically when there is sex with the main woman (s), when really this should only be part of the climax of the story.
When they could add many scenes both romantic, fun and hot (example: role play and cosplay, challenges between m and s for the attention of the mc, retake the card game but with scenes more h ...)
In addition to adding different routes to the end you want (like the classics see the brothers trying to hide their relationship from me, or looking for harem). Or something deeper as the family seeks the identity of their relationship either by hiding it or looking for a new home where they could act more uninhibited. Even going back a few steps and lengthening scenes from previous versions or adding more, at least personally, I would not mind starting it again if there were improvements in the future.
Maybe there are mistakes but the essential thing is to enjoy it and hopefully lasts many more episodes.
