Click the green flag, and *wait* until you get the girl's instructions. Type 'c' if you want to create a secret code message. Type 'v' if you have a number message you want to decode. Copy the code numbers by double-clicking on them and then choosing 'Copy' from the ... box. To paste a *number code* back in, to decode it, right-click and choose 'Paste'.
Thank you *oris_app*. I love your project! I have added a backdrop and some extra written instructions to help people know how to use it. (It will help if they can't hear her talk.)
