Just seeing this comment for the first time, sorry that I didn't respond earlier.
I'm ashamed to say I didn't make the connection to blood libel myself, and I wish that I had. The research exists and so does the start-up Peter Thiel is associated with, but you're right that otherwise the reports appear blown out of proportion, in part I'm sure due to the very anti-Semitic trope you mention.
As you point out, the game's been out for about a year now and I'm not actively working on it anymore. However, I'm still making a note to myself to revise these passages the next time I have the opportunity, because 1) I can, and 2) had I realized this connection when I was making it I'd never have written the jokes into the game.
(If any readers passing by are about to cry censorship: don't.)
I may not be able to update the game on other platforms/services, specifically Philomela (which is soon entering read-only mode) and Tap (which is handled by another company), but I'll try in any event. Any other websites besides those and itch which mirror the game are doing so without my consent so unfortunately there's not much I can do about them.
I want to thank you for bringing this issue to light, and also apologize to you and to anyone who may have been hurt by the game's inclusion of this awful trope. My ignorance is not an excuse and my intentions don't absolve me, but I can promise to get the content out of the game in any way that I control and vow to do better going forward.
