The answer to your question is: Yes, the guide will be updated.
Since Headpat told me he changed a few mechanics (like the corruption system) I decided to wait a bit before resuming working on the guide. Looking at what lies under the hood for the last update, I think I made the right decision. I'm currently working on updating the guide
but it will take some time as I'm quite busy these days.
The up-to-date guide should contain all scenes with up-to-date info, how to unlock every ending, explanations of how the new corruption system works, and more (including an overview of the scene selection algorithms and the percentage chance of triggering). This should leave no
Sana stone unturned.
