Thanks for the kind words and all the thoughtful input, it really means a lot :)
The sheep and wool idea is still very much in the brainstorming phase. There aren't any solid plans for changes to vegan/hardmode just yet. Right now, my main focus is still on polishing and expanding the standard mode. So for the time being, vegan mode will stay as-is (no backpack, no flask, no torch, no footwear).
That said, I absolutely love hearing your perspective, especially knowing you're a lifelong vegan! Your suggestions around alternative materials like hemp or flax are super interesting, and I really appreciate how you've broken down the different potential playstyles.
One idea I've been toying with is maybe having Bits and Bobs sell a simple cloth version of the backpack directly. Something with fewer slots (maybe just two) as a middle-ground option.
Once the core game is in a more complete state, I'd love to revisit vegan/hardmode and explore ways to make it a distinct and challenging experience without being too punishing.
Thanks again for taking the time to share your thoughts!
