It's the middle of the Cold War. A stranger gives you a magnetic tape, a note, and a number. They tell you to use your terminal to access a remote mainframe over dial-up and put together the conspiracies found on it.


What secrets can you uncover?

This is my entry for GitHub's GameOff 2024!

Theme: SECRETS

Wildcard Attempted:


In this version, there are 3 files in the secret directory. Good luck finding them! 

This game is Open Source so I'll be looking forward to collaborations and interesting spins!

The link to the GitHub should be somewhere...

DISCLAIMER: I'm not the one promising the $50k lol

PS: You can toggle the CRT effect with the  'CRT'  command

sorry to bother you again but is the congratulations password supposed to be mslqvydyjkxgyrq cause it's not working also, in the vigenere cipher file you said that P shifted by (Y=24) is supposed to be L but it should be N and that N shifted by (K=10) is supposed to be P where it should be V

I'm happy to reply your comments. You are very close to the password. 'congratulations'.txt is the hint. It was a curveball, but you are very close! Let me know if you cracked it.

figured it out... I'm dumm

Nah, you're doing a good job, as I said, it was a curveball

NOTE: The transposition cipher works by lining up the plaintext in 4 columns, with a minimum of 2 rows. Then you use X to complete the incomplete rows. Then you read it column by column. The Vigenere password is supposed to be:

vige

nere

= vniegree

I misspelt vigenere as vignere while encrypting it, so the password is 

vign

ereX

= veirgenX

I'm sorry about this, X should have double-checked his passwords. I will be fixing this ASAP!

You have to read the transposition cipher file. The hint is there

What's the password for the transposition cipher? It's not wudqvsrvlwlrq.

It is!

Ok, maybe it is. But the vigenere password is not vgnrieee.

Is the congratulations.txt password not mslqvydyjkxgyrq ?

You are very close to the password. 'congratulations'.txt is the hint. It's a curveball!
