Hi, tbh I've thought that it's just a poor copy of Living with the sister MW, but i actually see a huge potential in this game. As other person down below said: It would be much cooler to improve further relationship with the girls , make more interactions, balance out the battle system, add more events with each of them, maybe even add the opportunity to spend some free time after the guild work with the girls instead of immediately going home/ forest/ fight club.
Make them feel more alive ofc, cause right now , they are more like a living dolls, who's always ready to agree with you and so on. Oh and yes, pls fix the save system as soon as possible if you can, because just by moving this game into the different folder makes her forget about the existing save files, so you should always have it at the same folder for all of eternity. Hope your game goes well and you would be proud of your work. best wishes.
