Finished the Snap event. This was a lot of fun. Reminds me of the old days of Key VNs where they would have a lot of random stuff in there that would completely go off the rails the more weird choices you made.

So basically you should try to do every option at least twice to get all the dialogue. I think you can technically ace the entire Adventure in one try, but then you would miss a lot of fun stuff! And some choices needed to win are really out there anyway.

I love how there are several variations/reactions of Yukki in a swimsuit or her uniform for encounters even though it makes no difference for outcomes.
One of the best gags only happens if you go through a sequence THREE times. When Yukki gets affection points from Ruka for liking the food she added to the game and then rewards her with a boss song she sings personally... but if you die and have to redo that section Yukki's reaction to the food isnt genuine enough and Ruka denies her affection points, which bums Yukki out. So if you do a third run, Yukki will imitate her original reaction and celebrate when Ruka sings for her again. Absolutely glorious.

The ending was... confusing because it doesnt make sense that Yukki would have had that dream.
So in my opinion that's the original Yukki who actually went into a exhaustion coma from doing missions for Orchid. Full diving into cyberspace turned other members into vegetables linked to their computer, so basically the same thing almost happened to Yukki. But thanks to Ruka's music she was pulled out of her coma and woke up. For some reason it caused this unrelated 31A adventure game dream to happen, which is just something you have to roll with I guess. I think that was quite sweet actually... Ruka is her savior in all ways.

Because of this I do think it's best to play this after 5.1, but it might not be entirely necessary. KareTsuka dynamic and Megumi personality change at the very least requires 4.2.
