Allowing the player to use number keys, number pad to choose rather than just mouse clicks. Also, using enter or space to forward on single answers.
Sarahcumshot2 video has some glitch problems with it, might want to redo that one.
Clicking return on a phone contact fully returns you to the game instead of the phone screen.
A quick start would be nice, to put you post the acquiring of the lust, for people who are doing different play through.
Also, try to keep as much of the game to a single page as possible.
Additionally, found that the game throws errors if you open the browser console.
As an aside for coding. Keep everything in lowercase and without punctuation. Some systems/browsers will throw errors on if something has a capitalization in the code but not the image, so an easy workaround is to just never do anything other than lowercase.

An aside on the “saving” you mentioned. You literally can't do that with Sydney if you use a different starting stat. That feels more like railroading than the player having an informed choice.
I would also say remove any false choices in the game. Like whether you insult the class girl, or snitch on no one else coming to help set up, etc. It is the same speech/outcome anyway, and sure it might add “flavor” but it is so inconsequential.
