Hi Ben, I appreciate your comments.
Your first comment mentioned the PDF, so I thought you had already looked at it and I was confused how you haven't found the rules within it. As for your second comment, the link to the browser app on this Itch page is accompanied by the text "... you can play the browser app adaptation by Igor Zuber (still using the PDF for rules and story)..." - I'm not sure how I could say that the PDF is needed for the rules more explicitly. Or have you accessed the browser app link somewhere else? In any case, thank you very much for trying the game :) Hope you'll have fun with it now that you have access to the rules.
