Very good, a few tweaks would make it. – NSA CryptoChallenge Review

I'm liking it very much. It's a good cipher game. ***WANTS*** 1. I would like harder difficulties, including ciphered letters being the same as their solution from time to time (ie the encoded word "zje" solving as "the".) for added difficulty, rather than being able to anticipate what words ARE NOT based on their content. 2. There is a leaderboards/highscore system in already, however it does not function. Functionality would be great. 3. Randomly generated sentences for game longevity? There are lots of puzzles, but eventually I'm going to want more. 4. Cipher formulas and more tips, you know... unless you'd have to kill us if you told us. ***BUGS*** 1. Sometimes cryptos will not autocomplete when filled. May or may not be connected to use of the "check" button. The puzzle will be complete but not finish, thus forcing a quit. Also, if/when hint is used in this case, the game crashes. To be expected, but... 2. When you try to restart such a completed but finished puzzle, it retains all the letter you decoded, and does not solve. PERHAPS a "finish puzzle" button would help, rather than a possibly unreliable autocomplete. ***NEEDED TWEAKS*** 1. Menu buttons (Pause button in specific) are too close to the keyboard by maybe a decimeter. Overall, not too bad as the menu buttons have a confirmation request afterwards. Just a little annoying though. 2. Menus are a tiny bit scattered and seemingly mixed, but it's okay. ***FINAL OPINION*** Fun, challenging, and aimed right to the NSA career path. With a little education on how to complete the ciphers, you could probably hook a lot more potentials. Get the leaderboards up, and then monitor everyone's times so you know who to actively recruit. You might also consider making the puzzles cheatproof (no recurring puzzles, randomly generated sentences and ciphers, etc) for a honest online/talent hunting app. If that's what NSA made this for, that is. Otherwise, good app. Lotsa fun.
