Hello!! First of all, thank you so much for leaving such a detailed comment, I really appreciate it!
We are working on an improved version, and the typos will be corrected for sure! Thank you for pointing them out!
Yes, indeed Critique and Tractatus are named after two books by German philosophers! (they're named after the english translation, as I was more familiar with that). I'm glad you found the references!
(spoilers below)
Yeah Maria's mission was probably related to Critique, but she found Tractatus first. I initially wanted that to be said in a more explicit way, but I thought it would be more impactful if it was left ambiguous! There was a lot of things I wanted to be open to interpretation!
Thank you again for your comment!!
