Thank you for your suggestions. Your feedback helps shape a more immersive and personalized experience for solo players. I like the idea of Signatures as a way to better characterize characters without adding mechanical complexity. It's an approach that can help players define their style and bring more color to the narrative.
On the second suggestion, allowing players to write a previous line or action as a narrative device could be a way to highlight key moments without relying entirely on chance.
These ideas could add a rich narrative flavor without complicating the core mechanics. I'll consider them for future revisions or new editions - I really appreciate you taking the time to share your ideas.
