So, first the good news. Just finished playing, and the story and (most) characters are still good and enjoyable, for the most part. Some minor things I dislike, but it's more stuff I personally just don't like rather than bad writing. I do recommend this to anyone unsure if they want to play or not. The story is good, there's some nice emotional moments, the girls are varied and meet a variety of tastes, so there's going to be someone you like.
And the neutral news is there's an error in the bowling scene where Scarlett and Val are with you, and you have to skip over it.
Edit to put the bad news under the line break. Skip it if you're not interested.
Now the bad news. After replaying it, and trying an alternate route with different choices, I've really started to notice how linear it is. This isn't a game if you're looking for alternate events and meaningful choices that will affect the story. It makes sense, since the time travel plot means the player can't really do anything since the outcomes of a possible choice are already made earlier in the story. So just pick what you like, the only difference you make is 'get sex scene' or 'skip sex scene'. Maybe it's just that you forgot certain choices, like I skipped interacting with Tiffany and Val in their yoga sessions, and yet I end up doing yoga with Tiffany anyway. Or another one that sticks out is that I shut down the Krystal route right at the beginning, but even though she doesn't offer to cosplay for me, I still get the same screen saying she's gone off to get changed. And I know this is purely subjective, but I utterly HATE Riley. I hate her character, her appearence, and I'd be very happy if she died and wasn't in the story any more. Her scenes are a boring slog to sit through.
