Neat concept. Would be nice to know that you press X to start turning wheels. Also, I got completely stuck on the first non-given code; my first thought starts with a number that doesn't appear on the wheels.
Thank you :) I'll add a prompt for using X. And I know what you mean with the puzzle, global number differences foiled me again :D Here's a bit of help in ROTR13: Gur pbqr vf Rhebcrna, abg Nzrevpna . But I will probably change that code, so there's no confusion :)
Ah, that figures; funnily enough, I did think of another possibility based on that, but it started with the same number since I'm only familiar with the ones from the USA and UK. Thanks for your response, finished the game and loved it!
