Back for another comment and I hope the dev sees this.
This VN is what made me give 3d-cg another chance. I've commonly found it to be pretty ugly but I do in fact like the characters in GM.
When it generally comes to harem shit, it feels like the main character often is quite full of himself or just insufferable but this was such a completely nice change of pace. The main character clearly shows how important the cast is to him and he does his very best to split his attention between all of them. I've been following this since 0.4 (I think?) and I frequently eagerly await the next major update.
When you have a VN that goes on for this long, I think it's rather important that you make the player/reader care about the caracters and look forward to their unique interactions.
I absolutely love this. The only minor complaint I have is that it feels like 95% of the current chapters is sex, which normally wouldn't mind but when you've spend this much time working on all the characters, it feels like such a shame to not have more family developments and see how much they'll all further grow together. I can't wait to see this shit to the end.
