Yeah the stamp makes her your ally, speaking of Himari, I've asked this before, but I don't think anyone responded. I remember on an old version getting an ending where she somehow magically traps you in her manga, you live out the story of a feminized brother dealing with his little sister using a wishing maguffin to turn him into a bimbo older (then younger) sister, and eventually get trapped in the book itself. (iirc) The last scene was you peeking through a hole in the wall of the locker room to spy on her gangbang I think. (also it might not have been actual magic, just hallucinations, but w/e)
Does anyone else remember this? Or know how to trigger it? No idea why something so magical was in this game, but I liked it tbh, dev could totally do more wild stuff like that.
I have a few gripes with the game, but overall the only reason I don't sub to the patreon is because there's no sex, unless it's been added since I played like a year ago. The buildup of each ending can be really good and well done, but then there's no, well, climax. Arguably the story "climax" is the 'a few months later' scene of what your life has become, and that's a good narrative climax, but outside of "cursed to edge for life" edge cases, porn games just need a real climax to finish to, in my humble opinion.
Perfect example is the first Himari ending, if you end up as her replacement, the game basically says outright that you'll end up in a brothel once you get too old, but then fades to black. It's a total waste of all that buildup, when it would only take one more scene of a night in that brothel to cap off that story with the perfect narrative and sexual climax.
I know the dev doesn't want to add sex, but if you ever read this, please consider adding it as a toggelable option maybe, I can't speak for anyone else, but I'd sub to the patreon, and I bet a lot of other people would too.
