About the "harem club", I didn't understand the scene when I saw it in the game, it was weird to see that, and I don't think it should be there, I only understood it when I read the comments here, and the guy being mocked is probably someone who is already on my long 'ignore' list, because I have no idea who he is.
I think if the dev wanted to mock the guy and people like him, creating a short comic and posting it on Patreon would be enough, someone would have posted it here and whoever cares would have found it funny, but as some said, the dev should think bigger, and consider that 99% won't understand, and this specific content can negatively affect the general opinion of the game on platforms like Steam, I'll just post some SS from the game, I think the dev will understand it better that way.
Canon content in AVNs usually shows characters in the background, who are there, but are not part of the story, but in this game it's not like that, the characters in the story interact with the canon characters, something I don't think should happen; A few months ago I commented on a character, but only later did I find out that it was a canon character from another game and not someone who is actually part of the story, which distracted me... it might just be a personal opinion, but that's my opinion.
About the update, I thought it was weak, I like the game, but this update felt like filler to me, we didn't see any progress in relationships, maybe with Fame, but only maybe; the renders avoided showing Parker for some reason, she was there, but the renders focused a bit too much on the protagonist, I don't even remember Parker's face or what she was wearing; Yuna appeared, but she was in the background, she just happened to be in the protagonist's room, but the focus was still on the protagonist and not her; the only other character we might have seen progress with was Ria.
About American football, I don't know much about the sport, and I'm not interested in learning about it, so I'll avoid talking too much about it, but the dev needs to remember that it's not a widely popular sport, and all that content and conversations in a short space of time can be a bit overwhelming, so many things were said that I don't understand and mentioned so many people that I've never heard of, that I ended up simply ignoring and skipping those dialogues; I would enjoy it much more if there was less of that and more content with the LIs, after all, I'm here for them.
Anyway, I like the game, but due to my expectations, this update was disappointing, I wanted more scenes with the LIs, more progression in relationships, especially with Yuna, I'm not interested in Fame and had even avoided her before, but I remade my save saying "yes" to all of them simply because I thought the update was weak.
One criticism I have to make is the huge amount of "exceptions" I encountered when clicking through the interface, and honestly, it's worrying to see so many problems like that, and it's something the dev could fix in a day if he wanted to.
