I'm terrible at card games, but my strategy here was hit the "end turn" button until I had all the body parts in my hand, placed them on the table and used the necronomicon card (that appeared while I was trying to get all the body parts) I noticed that each part doesn't lose freshness in the hand so until i needed to put them on the table i didn't want to.
That seemed to work? but i'm not sure i'm playing as intended.
I love the style of it though, nice creepy atmosphere and definitely on theme :) good stuff!
