Just a couple of suggestions for things to be added. Nothing story-wise, but more just functions.
One: Allow me to export saves. I typically play these games on gamcore on my phone's browser in incognito mode, and sometimes the cookies reset, so I will lose all my saves. I think adding a save export and import function would help out with this. It could also be something that you could use to transfer your choices from the first part into the second part, or the second to the third part.
Two: Add a gallery for scenes that cant be repeated. Like, it would be a way that the player can replay events and possibly make different choices, without necessarily affecting your original choices, in case the player wants to view all the images.
I don't know, just some suggestions that I think could be some quality-of-life improvements.
