Howdy, folks! People here and there have been asking about getting some kind of guide to the routes available in the game, and after a few aborted attempts I've finally been able to put together a flowchart~ It's a bit messy-looking, but hopefully it does a good enough job of illustrating the story progression and key moments in the game, as well as providing a handful of development notes I added while I was making it. Also, the green nodes mark the sections that are all-new to the current version of the game in case you downloaded a previous version and want to see at a glance what's been added recently.
Seeing the game laid out like this really shows how far this game has come since the start of 2019 when it was basically just the purple-marked Delusion route. It's so BIG!
I hope it helps someone! I'll be regularly updating this news post with more up to date guides in line with future releases, so be sure to check it out if you get lost and download the latest guide from the attachments below.
