Some time ago I've seen someone online use this Chapter 1 dialogue to justify Ralsei being British:
Alright, this lift should take us out of here.
Now, it might take a while, so...
Get comfy, everyone!
So I decided to look closer into it. Long story short, he probably isn't British, and it's just a quirk of Toby's writing.
The game consistently uses "grey" over "gray":
Sorry, the "grey" spring is blocked up.
— Tenna if you photograph the green spring, Chapter 3, Board 2
SHUTTAH - When its eyes snap shut, memories are made in grey.
Normally, my photos are all grey...
— Shuttah after being spared, Chapter 3, Board 2
This is a Kingdom without King or Prince.
Flaky disciples, lost in meaningless worship.
Old scholars, greyed by research forgotten.
— Cuptain, Chapter 4
On the other hand, the game consistently uses "favor" over "favour":
Ho ho ho... if it isn't my two favorite people.
— Lancer, Chapter 1
Well, if you are a fan. Haha. Could I bother you for a favor?
— Mettaton, Chapter 2
The secret lawnmower game! Everybody's favorite!
— Tenna, Chapter 3, Board 2
She said I should call you, um... a "noob."
Apparently, it means... your favorite person!
— Ralsei, Chapter 4, Library room with an octave-shifting piano
And "center" over "centre":
Today, the FOUNTAIN OF DARKNESS-
The geyser that gives this land form-
Stands tall at the center of the kingdom.
— Ralsei, Chapter 1, The Legend
Rule of thirds? No! Try to center your target, folks!
— Shuttah, Chapter 3
(... huh!? The center of gravity has shifted...!)
— Bowl of candy if you try to take 2, Chapter 4, before Gerson's Study
It also almost always uses "defense" over "defence":
That ribbon is ARMOR, Kris!
It increases defense.
— Ralsei reacting to the White Ribbon, Chapter 1
DIDN'T YOU KNOW [Neo] IS FAMOUS FOR ITS HIGH DEFENSE!?
— Spamton NEO, Chapter 2, Weird Route
Yeah, that's good enough. He can make a pillow fort.
That's better than a bed anyway. More defense.
— Susie after stealing a pillow from the couch, Chapter 4, Library room with an octave-shifting piano
Except for the description of the Bounce Blade, for some reason:
A pink saber with a rubber blade. Weak, but increases defence.
