So... bug report:
I simultaneously ran out of health tokens and overfilled my token capacity. That's what caused the bug. (Probably reproducible.)
At that point, the city guard popped up. ...and popped up again. ...and popped up again. An endless loop, never letting me respond... I only had one possible action...
I used my power. Repeatedly, until I got below my token capacity. The city guard went away, and Death appeared.
I corrupted Death. Two shiny corruption tokens, netting me three health tokens. Death went away... and came right back.
Hmm. I gave him some more tokens... he came right back. I gave him some more tokens... he came right back. I gave him my last three non-health tokens... he came right back.
Now I'm sitting there with a full inventory of health tokens, four of them shiny. HMM...
...I corrupted him with two shiny health tokens. City guard comes back. I give him all my new charisma tokens, and the extra health token.
Death reappears. And then... with a full inventory of health tokens...
...I accept my fate.
