Agree! And for the arch shapes, it reminds me of the “slogan” of the game: “Breaking cycles…”. An arch is kinda like a broken circle.
And hilariously (context: I’m not a native english speaker), I only today learned what “arch”/“arches” meant and I’m now, in a way, seeing it in other places (as in, the word) :P
For the Flynn route being canon, I think Jose Forest makes a decent argument about it not being so, but I still wish there’s some Flynn-related visions as well.
