Code:
1b 7a 6b 3d 8a 7b 3b 9b 2b 1a 9a 7d 6a 8d 8b 4b 2a 6d 5b 5a 2d 5d 4d 4a 3a 1d *b *a
12 10 10 10  9  9  9  8  8  8  7  7  7  6  6  6  6  6  5  5  5  4  4  4  4  4  1  1

So there's 26 unique characters, so we probably just have to assign the right letters to these.

Surely that's not an english plaintext, frequency distribution doesn't fit.
We can try a bruteforce and see if something show up.

Brute force is against the "rules", no?

I mean, trying to replace every symbol with a letter, for all the possible combination, and observe if one of the obtained plaintext has something intellegible in it.

Frequency analysis instead can be used, if we can take out weird parts or repetition

Well, 26! combinations, good luck with that

a brand new account just to say that?  Grin

Yeah, I thought that post deserved an answer.

Anyway, just wanted to point out that the text adventure is called "Days Destroyed". It might be a reference to "Bitcoin Days Destroyed"?
