So, I've played the last version. I'm going to be honest, I expected a lot more content in 0.1.1 than 0.1.0. I do understand that you were finishing Husband Phone and that Graduation was in hiatus for a while. I also understand that you were busy working on new features like the Smashchat and the addiction system that goes with it, but to me, after going back to replay 0.1.0, it seems the old version was fine. At least, it was fine for the content it had and for the content 0.1.1 adds. And if 0.1.2 is already on the corner, I don't expect a lot of content is going to be added. Which make preordering the game kinda bad, since you would expect a good amount of content being added to justify it, but if all you get is 2 small story updates, it is disappointing. Yeah, we get a UI update with new functionalities, but they do nothing that is interesting for the story at this moment.
Now, talking about the new design. I dig it, the video preview you did before the release gave me hope that the release would be good. The UI is good looking, the systems seems to be working and it is responsive in Firefox, which is not always the case with some HTML games out there. However, since we have a setting for the music volume, it would be nice to have one for the rest too. Personally, after hearing the ping/bubble sound a dozen times, I'm kinda over it and IRL I have it mute in my phone. For when we call other people, it would also be nice if we could adjust that sound too. Since it's in a browser and not in something like renpy, it's kinda frustrating to adjust the volume in my sound mixer which affect the rest of my tabs.
About the constant reminder when you are in whatapps and lust get added to you. I don't think it is needed to remind us everytime that we can go in Smashchat and look at your status to see the change. After the first time, it should be enough and it is probably just a oversight by you. There are also a number of typo that I've seen and some sentences that are just missing word to be completed. I could go find them again and send them to you on Discord/Patreon or even here. I can probably do one better and tell you at which line in the story.js the errors are. It's nothing gamebreaking, and totally normal if you don't have anyone that proofread after you're done writing.
As for the story and the choices you make. Well, the premise is fun, you go away to uni and you old bully/drug boss reappears in your life. "Darien" grudge against you makes sense, you fucked him over to get out of a bad situation, which is fine. Howerver, like Zobra already said, him revealing his plan doesn't make sense, especially this early. It would be better if he tries to friend the MC or at least pretend to get on his good side while in the background he is corrupting his family/girlfriend for his planned revenge. The MC could still stop some his corruption by making the right choice. An easy exemple could be : MC sister is asking MC if she should go out to a nightclub with Darien, MC has 2 choices, "Yeah you should. It would help you get out of your shell a bit."/"I don't think you should. I'm not sure Darien crowd is a match for you.". For each choice, you could add why the MC feels that way : Yes, go out! "Darien actually has been nice since he moved in, from what Natasha told me, he doesn't flirt with her and he has been helping mom with the house chores."/ No, don't go out. "Even though he seems to have change, I don't feel like going out with an ex drug dealer would be the best for Isabelle. I'm not sure it's the best crowd for her.". By doing it this way, it would feel more organic and you can still reveal later Darien's plan. Also, you could still make so your sister goes out anyway. Like, she can bring up that Natasha is going too, so she isn't going be alone with him and his crew, etc. So, you can still remove having to choose for her, but still making it feel more natural. The MC should trust his GF, unless he has reason not to, so he has no reason for his sister not to go out with them. You get what I mean? To continue with the choice we make right now. It does seem that it don't change anything right now, but it is also early in the story, so I wouldn't expect them to have a lot of weight for now. Still, if you keep the story as is, the first choice with Darien should have an immediate impact, if you confront him, then it is okay to tell him he has to get the fuck out of your family house, but if you choose to beg him not to do anything, that you are going to do anything for him not to corrupt your family, than you should not have to ask him to get the fuck out, it doesn't make sense for the MC to be begging him one instant and suddenly growing some balls and acting like a top dog. Like, there's maybe 3 days passing by with only the MC going to a "rookie" party, and with what we see, the only one he told about the situation is his bestfriend and that one didn't told him to man up whichever choice you made previously. Anyway, that just if you keep the story as is. Which for me personally, I think would be a mistake, I think it can be improved significanly or at least made so it's more grounded.
With all that said, I wish you well on the continuation of the game. Good luck, and I hope it can last till its graduation!
