Sure, I'll change up the list level bullets in v0.3.1! I can see how they'd get visually confusing, especially with the lists now being spread across two columns.
In re the Assassin, I hadn't put any specific thought into what happens if/when you manage to kill your Prey. In a real way, you've got a lot of mechanical incentives to keep them alive - they give you access to a higher-tier faction's resources, they can generate XP for you via the connection clock, etc. It is somewhat unsatisfying if you just lose a playbook ability for doing the thing your playbook is nominally about, I'll admit - I haven't yet figured out a good way to reconcile the fact that the Assassin is, conceptually, about not yet having gotten your revenge, with the inevitability that you will at some point get that revenge. Swapping the Prey over to another faction seems like a pretty straightforward and generally workable solution, though. I'll think on it and put something in the next update.
Thanks for reading the game, and for bringing that stuff to my attention! ^___^
