I've been meaning to make this a post here, but I kept forgetting to do it.

Since a lot of people in here have found it useful during previous version updates, I figured I'd make an actual topic here in the community board with a link to the Google Sheet I made about a year ago, so that people can look at it whenever they need to.

The link opens on a tab that just has a title screen image to avoid spoiler territory for those that don't want things spoiled for them. This Google Sheet link contains the following:

• Gallery image locations: Where you need to go in order to find the different locked images in the Gallery. As updates come out with new images, I add to this with the locations of said images.
• Shoichi notes: Information on how to access the three "Path" splits that occur within Shoichi's route. If you want to see a specific "Path", you can use the information here to obtain it. This also has a note regarding a choice that happens with Saya a few days after the "Path" has been decided.
• Keisuke notes: Information about a set of choices made on the date on Day 26 and whether or not it ends on an awkward note.
• Haruki notes: As of the time of this post, this just details how to unlock his route on the character select screen for those who, like myself prior to writing this, didn't know how to access it and had to get assistance from the unofficial Discord server.

If I come across something during personal playing of the story in future updates that I feel would be useful to add, I will add it to the appropriate section. I hope this Google Sheet link continues to prove helpful for current and future readers.

I have made some adjustments to the Google Sheet I created. Namely in the Image Gallery tab. It was getting frustrating to have to individually move and shift every image and  cell to properly place a new image when one has been added to the visual novel. As such, I've arranged the sheet so the images are in a single list rather than trying to keep them in their '6 per page' format they were in in the visual novel itself. The images will still appear in their proper order, but this will make it easier for me to add in future images as more come out.

Also the main page will now list what version I currently have the Sheet updated to, and what, if anything, has been updated in the sheet itself. As of this post, it us current up to Version 0.75, Haruki's most recent update, which has one new image to unlock.

Please remember, however, this is not an official guide to the VN, and should not be taken as such. These are just what I have found, or have been told, through my time of playing the VN.
