That's such a wonderful reference! I didn't know that ecdysis was the biological term for an insect's molt. I learned something new thanks to your game.
I also absolutely love the visual design. It immediately puts you in the dark atmosphere of being an assassin, while the rules remain surprisingly easy to read and understand.
The system itself is really elegant, and I think I'll have to give it a try soon. I especially like how your character constantly evolves by gaining, losing, or even borrowing traits and skills from the people they encounter. It makes the journey toward revenge feel like a journey of self-discovery as much as one of vengeance.
Congratulations on a really clever design!
