I have a few suggestions
1) The ballista really isn't worth it, 300 gold+5 gold per ammo over the rocks to kill 5 more orcs vs the rocks. I think even 50 orcs wouldn't be worth it since the resource grind is already very tight and you need that gold elsewhere so I can't think of a fix for that without making it overpowered.
2) When its implemented have Hudson come to you for the villagers problems, having to waste 1 energy/save scum to check with him every day would be grindy or make it every 5th day or something where he will have something for you if that's easier.
3) Chatting giving +5 sanity would be pretty nice, as of now with the window being so tight I found myself just designating one girl as my sanity bot since you need to spend 2 energy a day just to stagnate on sanity so I really didn't have time to chat.
4) The current resource grind is very tight, I min-maxed gold upgrades/grind early and was still barely making it on the 3rd week. I had little to no room to increase respect or charisma or chat with the girls. A fix for that would be similar to the first game where its a pretty tight window to get through chapter 1 but then you get a nice boost in resources after surviving but you're no doubt still playing around with a ton of numbers on that end.
As for requests I don't really have any I just prefer dedicated endings or routes for single important girls like Miliyra or Laura, it would also be cool if the Guard that helps you escape is a character since he cuts off as he gives you his name and I'm really looking foward to the Steven/Charles side plots since they were badass in the first game :).
