Hey there, thank you so much for trying out our game! Really sorry to hear that the rune grading is causing so much trouble - yes, the first customer should be just the fish rune. Want to make sure we understood correctly - for carving mode, you're suggesting having the stencils themselves count as having made the rune(s), right? We'll pass your feedback on to our designer and programmers and discuss solutions as a team :)
Thank you for the suggestions on additional story elements as well. We didn't have time to put in as much branching narrative as we wanted to, but we're happy to see there's interest in having more!
