Suggestion - Scool Mode

You should have a "chapter" called "School-mode", where you have infinite ressources, so that you can test/learn the crafting system before actually playing.

Maybe also have a seperate part of the school for testing gems.

This way new players can get a better idea of what is worth keeping/using and how to get an optimal build in their own viewer.

Non of this should ofc carry over into the actual gameplay.
