I'm also confused about the Haley ending because according to the walkthrough, you need >=80 points with Haley, but the guide only shows enough choices to get max 70 points, so I think it's currently impossible?? Would love to hear from anyone if you were somehow able to obtain Haley's ending ! (edit: I followed the walkthrough to get all possible Haley points and did acquire their ending, so I think the threshold in the guide must just be a typo.)
Ahh sorry you're frustrated with it, totally fine to take a break from it. If it helps though: the walkthrough/guide is a .PNG file located in the Download section (underneath the game files), named: BSH walkthrough.png (98 kB). If you Ctrl+f to search "BSH walkthrough", you should find the place on the page to download the image file. Hope this helps :]
