Absolutely loved this. Cracking codes and unraveling all kinds of cryptic messages, very very cool
Its a really good game about ciphers and cryptography
Such a fun puzzle game, loved it
i have no idea how ratings are only at 74% considering it's literally free
👍
i like that its deciphering cryptocodes
The main character is well developed, and I like the way her story was told. The puzzles are easy at first but the difficulty ramps up towards the end: the q bomb ciphers and the bonus ciphers are too hard for me. I would have preferred the UI to be better, and for there to be better hints, but as a whole for the price its pretty good. I would recommend this to people who have some form of experience cracking ciphers, because the way the game teaches you to do it is not good. When playing, have a word finder/unscrambler on hand, as well as some pen and paper and you should be good.
This would make a very fun high school assignment, but is a very boring game. I thought I'd enjoy the decoding puzzles, but the story, the hints, the challenges... honestly it's all as dry as the Sahara. Don't do it.
This game is awesome! It has been a while since I last played, but I'll try to give a rundown. Spoilers ahead potentially. [spoiler] You decode a cipher in a newspaper and get recruited into a government agency which is dedicated to decoding ciphers. At the time you are recruited, they are attempting to catch a terrorist. [/spoiler]
