Ah the way the questions were worded kinda sent me to believe it was difficulty in regard of attacks and enemies lol at least the assumption paid off a little~ And I am kinda glad that i was wrong here. A recent-ish trend of games like this tie events that are only viewable in higher difficulties. Its a weird thing to add in games of this nature.
There were some other interesting bits of information in the manual that kinda raised an eyebrow. Like the possible identity of the person asking the questions at the beginning of the game. Though i fear if my hunch is right, it's spoiler territory. The animation for the game that came out last year kinda fuels that theory. [besides some contradictory things in regards to the Tentacle enemy]
If I find any more useful stuff I'll post it here [along with the fakku discord]
