So...anyone have any ideas? I'm not at my PC right now to grab the info for the blocks in the starting area.

My first idea is that it's a Beale cipher. Each number would stand for a letter and the key would be one of the texts in the game.

It's not very likely, though. The distribution of the numbers is odd for a Beale cipher. The range is very narrow (the smallest number is 184 and the largest is 222) and most numbers repeat multiple times (for instance 200 appears 3 times and 207 appears 5 times).

Maybe they are coordinates to the letter blocks. Maybe some kind of character coding that is not ASCII. Possibly related to the final puzzle after the challenges.

It might be a homophonic substitution cipher, where multiple numbers correspond to the same letters. But if that was the case, I don't know why they would start at 184 and not just go from 1 to 39...

Also, if I remember correctly the final challenge has a block of 13x17 letters and numbers, so 221 in total. The achievement numbers go to 222. Coincidence? Probably.

[Boss: ✖‿✖]

Does anyone know how to go about these extra challenges?
Also, how could you validate them?

Did anyone ever figure this out???
