I'll agree with others that being brutal on the early raider actually stood out a bit more to me, and was not a problem. But the Dev's vision is the most important part. If they heard or learned that some people were put off by the sudden brutal nature of the scene, they fix it as they like. If I understand the dev note correctly, something similar is going back in later.
I'll continue to support this game, as it has a lot of great potential. While there are lots of male Dom games, so few seem to do it at a high level. I love that this has a much more lived in feel, and I'm not starting from scratch (again) trying to properly train these women from nothing. The MC's rough edges feel appropriate for the setting, and for where things might go. If we meet our Wife's sister, and if she has grown daughters of her own, we may do more of the 'training' seen elsewhere, but I am hopeful our MC will not be forced to have emotional obstacles to overcome to get to the good stuff.
