Thank you! The omission of a tutorial is an intentional design choice. When I was first learning redstone (the inspiration for this game), I got such a sense of wonder out of experimenting with all the bits and figuring out how they worked. I want that same feeling captured in TUNG, and I'm concerned that a tutorial in the traditional sense would take away from that.
That said I really appreciate the feedback. Before the release of the full game I will definitely look into a firmer tutorial than the demo world I have now, but I will be very careful in doing so.
I'm so happy you enjoy the game :)
