Hello guys,i've wasted the last few days on the puzzle,and I still haven't made any real progress.
I've practically given up,so I guess I'll try to give out some information that I found useful.
I mostly tackled the text adventure game,checking out combinations on the keypad,by combining the information from the qr codes and wikipedia articles.
I think that the sentence "The journey inward begins here" is very suspicious.What picked my curiousity is the fact that inside the game you are specifically told that the map holds the key. When you check out the map,you get the clue that "The journey inward begins here".
The "" at the beginning and end of the sentence means something.It's used so it can seperate the needed sentence from the unneeded information.The part inside is a code,further evidence of it being the fact that without the spaces,its length is 26 letters.
I tried decoding "The journey inward begins here" with
http://www.dcode.fr/tools-list#cryptography most of the tools listed here,however most of them needed something like a keyword to have relevant results.
I also think that there is a magic number in this puzzle,and that is 26.
It pops up way too many times,you can find it everywhere.
There are 26 letters in the latin alphabet,so apparently you can assign a letter to a number,hinting at the use of substitution cipher.
What if you crop out the white triangles from the picture?Could the result be a usable code?There's no evidence to support that,but I was curious about it.
Anyways,I wish you guys good luck,I know that most of the things I posted are conjecture and speculation,however I'm not that good in puzzle-solving.I actually haven't spent time on the puzzle in like 3 days,so most of my theories are blurry,but I thought that they could be of use to someone else.
