Tentacle?

I wonder what the TNTC would mean in the City's Story.

Oooo nice ^+^

You are right about the names; the girl´s name is revealed in the game description at the store page, the boy´s name by deciphering the alphabet.
I always saw the subtitle as "Miku and Taku", but now that you mention it, there is nowhere a clue to be found that the + translates to "and".
"Miku heals Taku" absolutely makes sense; I wonder if this was the dev´s intention.
Thanks for sharing your thoughts, very interesting.

Also, if anyone is interested, I took a look at the game's subtitle, which I think translates to:
M I K U + T A K U
I couldn't see a similar + grapheme, so I'm assuming it's literally a +, meaning 'and', or alternatively referencing the + see in the pictographs, meaning 'heal'. This leads me to believe that the girl's name is Miku, and the boy is Taku. Sorry if that was already obvious.

I´m glad it is useful to you; thanks for letting me know.

GG thanks for this, gives my a direction on terms of interpretation that I hadn't thought of.

Puppy ^+^

Hmm, very good one, Eddie, thanks. I was focused on my first idea, + as positive as Miku is infected upon arrival, not knowing/caring, as the sign sticks above her head but your explanation makes more sense.

Taku is injured, the cross could symbolize the need for medical help, Miku begins to search for it.
Some suggestions: ND-Need, HL-Healing or Help, WR-Where, FN-Find, CT-City, MS-Mass(?)

Any guesses what last 7 words of Our Story are..?
