Initial report: Good, fun, worth it.
In my case I have all paths LIs and sides saved already where there was no other influence from other LIs or sides (this is a lot of save paths). And, after a few hours on just the Jill path, I still have a long way to go. There is a LOT of content (as some stated before).
One scene where even if you are not on her path, you get to help Rio, who is a bit sad, feel better. It was very touching and heartwarming.
I spent the first few minutes just looking at the intro slideshow. Excellent. Anyway, hope you all are doing well. Take care.
