I've never really built a sky factory before, but so far this game has effectively communicated that if I'm getting tired of doing something one way, it's probably time to look for another method of grinding resources.
I do have one major complaint thought: what's with the lack of a crafting grid? The crafting system as-is may be more user-friendly for beginners, but I hate having to go hunting through four pages for an icon that's blending in with all its buddies or else keep switching my hand between mouse and keyboard. When I get there, I'm doing extra clicks than feel nescessary. When I think about it critically, I realize this is an improvement over the Minetest default crafting behavior. Perhaps I am again hearing the call of the game telling me I'm doing it wrong, and should invest in my actual sky factory.
