Hello Chankir, thanks for playing the game so far! To answer your question yes, the courtship is the entire game - it ends with the (almost) titular Fete of the Squire in which the knight picks their successor, namely Leith if you've got everything right! I have considered the actual squire part as a sequel, but that's a distant dream for now I think.
Thanks for pointing out that bug, I'll look into it and see what can be done in the next build.
Thanks also for pointing out the Patreon link problems, these should now be fixed!
