Ok the good things first. The sister character is hands down the best thing about this game, especially before the mother comes into play. She is smart, attractive, and funny and is a great love interest. The relationship that the brother(MC) and sister start having and cultivating before the mother shows up is wonderful. I really did wish that you could have gone through this game exploring this relationship without getting the mother and her cronies involved. The sister is the only reason why I am giving this game two stars.
So now the bad, and there is alot of it. I just gotta say first off the mother is straight up cancer and her cronies (Vicky and Emma) are not much better. That is more a personal gripe than anything. Anyways, the biggest problem with the mother in regards to the story of the brother and sister relationship is that there was no way to keep the sister from getting corrupted by the mother. You literally had to ask for the mother's help with the sister to progress the game, even though you know full well what type of person she is and what her help will entail? If you did not, the player would be stuck in a neverending loop of repeating the same scenes over and over again, almost always with no clear indication of how to break out of it. With all that aside, it just felt like bad storytelling, especially if you were not trying to pursue any other relationships. Also, you could get to the point in that relationship where you see each other naked and even perform oral sex on the sister without asking the mother's help. But the sister was still too shy and needs help to open up from a clear sociopath? It just made no sense to me to even include the mother at all when the MC clearly does not trust or like her and knows she would do more harm than good. I will say it again, it was bad storytelling and writing, which had it's own issues, grammatical and otherwise.
So another major issue is that this game does have that grind where you have to build up points in certain things to progress the game. Normally, I don't mind a little bit of grinding if there was some reward to it. But when you combine alot of grinding and the inability to progress the story because you somehow missed a decision or a scene or a random event or any of the other slew of things, then the neverending loop occurs. And you are sitting there scratching your head, trying to figure out what to do next. I experienced this and finally broke down and used the walkthrough, which still included alot of grinding, because that is part of the game. This was one of the reasons why people were asking for walkthroughs so much in the comments.
Finally, the game still has bugs even though it is labeled as complete. Make sure to save often, because I ended up having to go back through things because I would try to do something as simple as go into the storage room and it would kick me straight the title screen. I would suggest the developer go back and clean up the bugs in this game before continuing on with the sequel.
TLDR: Overall story is not very good, no clear indicators on how to progress the game, alot of unneccesary grinding, high possibility of getting in a neverending loop of repeated actions with no clear way out of it, game breaking bugs still exist in this "completed" game. The best part of the game is the sister character before any corruption from the mother takes place.
One last thing I will say is that it has been mentioned in the comments that the sister's pregnancy is not actually achieved by the brother, but secretly achieved by some random asshole recruited by the mother. All this being done behind the scenes, so the brother is none the wiser and is taking care of a kid not even his own. I have no proof that this is the case, but if it is true, then I (and the ones who pointed this out) feel that falls under the classification of NTR. Therefore, the game should include that as a tag. I say this not only because I am not a fan of NTR, except for extremely rare cases (this not being one of them), but also as a warning sign for those that want to avoid this content. Once again, only if these observations are true. I did not get that indication when I played, but figured I would throw this out there.
