Are there hidden codes, or was this feature abadoned?
To be fair with you we kinda forgot about this ^^ but we are preparing a replacement/possible extension in the newest version, where you will be able to find special codes inside of the game! They won't be easy to find, that's for sure, but can add a nice variety to the pool of items you'll be able to get from new features such as
Quests. But for now we should keep our mouths shut and not spoil the new features
