Hello Solz!
Do you say in the game? If it is, we're thinking about it for future releases.
Now if it's an online guide... Since the game is constantly developing, bringing new content and mechanics in every new version, and as we have a tiny crew, we are dedicating all our time to the game's development. Stopping to develop an online guide was going to be tricky. But we don't discard out this idea and one of the members will start posting tutorials on our Reddit community. Soon we will update our page with the links!
One of the things that are working well is our Discord community! We have a #spoilers channel, where people ask how to get things and we respond very quickly.
As is the case with the barn key. We haven't finished implementing this part yet. But we are bringing news (hot ones) now in version 0.5.0 which we will release soon!
