You can't save during choices, save always before them.

Press F8 to enable auto-skip.
Note: Regular skip is - most of the time - faster than jumping to next choice.

✧ What if the corpse had something contagious?
Note: Skip normally here. Using jump-to-next-choice after the previous choice will make your game crash.

I made the mistake of crashing it then and now can't get past this choice even by reloading way back. Did I permanently lock myself out of some routes?
Jane Jane 13 Aug, 2022 @ 7:04am 
How can you save before any choices? I mean, how do you know that there will be a choice in next text? Thank you.
Lita 29 Aug, 2021 @ 11:33pm 
Is there actually any real point to the choices of 'write in my diary' or 'read a book'? They don't really seem to have any impact on the story, do they actually matter?
Leah 13 Aug, 2020 @ 8:00pm 
Wonderful guide. I've collected all the CG for it, but I'm missing the bottom left movie. Anyone know what/where it is?
Shess 20 Jan, 2020 @ 10:47am 
Maybe it'd be a good idea to add in the "Notes" section that Jack's and Lupine's routes (as well as that blessed "Skip all!" option during the picnic) are simply unavailable until you get at least one good or neutral ending. "A Performance for Three" will unlock them, by the way.

Until then - no matter what you do, all your choices will simply be ignored and the game will railroad you towards the nearest "nice guy" option (Watson, Holmes or Akechi).
チェリーパイ CherryPie 1 Oct, 2019 @ 12:19pm 
Great. Thanks for this guide.
IBJamon 3 Sep, 2019 @ 7:32pm 
I hate to reply to myself, but I figured it out. I needed to watch all of the scenes for the picnic at the park. Apparently I somehow missed Lupine's.
IBJamon 3 Sep, 2019 @ 6:09pm 
This guide is wonderful. However, I am missing the top right gallery panel under Lupin; it's the only thing keeping me from getting all achievements. Any idea how to unlock this?
lylat  [author] 23 Aug, 2019 @ 4:49pm 
This is an optimized guide and must be followed in the shown order to reach all the possible endings. If you start with Lupin's route, you'll skip many other required choices/events to reach there, and that's the reason why "Skip It!" option isn't showing up for you.
Yandruil 23 Aug, 2019 @ 3:55pm 
Maybe I am required to finish a different ending first.
