Add Haley game folder to your AV exceptions and extract downloaded game zip again. Apparently your antivirus detects it as false positive and removes it without telling you.
Because it's pointless as it's a story based visual novel.
For some story based VNs (visual novel implies story though I would think) it'd still be useful. For example if the story had multiple paths/girls and updates didn't always focus on all of them. I don't really want to grab an update just to find out my route of choice received two minutes of content.
I think he's asking more so that he has some kind of idea how much new content there is and maybe whether or not there's new content with a particular girl in order to determine if it's worthwhile for him to download this version or if he'd be better off waiting for a future one.
Unfortunately this is one of the handful of dev's that don't visit here and where the changelog is on their patreon (or subscribestar) site. Unless someone here has an account there, no changelog seems to ever get posted here.
Nope and because of how the story is written there more than likely won't be any content with her.
