Good news! The playtest went very very well!
I've got soo much feedback I'm overwhelmed. The core mechanic works frankly better than expected, so that stays, but I've written down a lot of things we discussed as a playgroup while handling scenes and discussing the themes of the game. Food (as a unit that needs to be tracked) goes.
I've now pretty solid ideas and a direction for the game, what I need is to rewrite and put down my scrambled notes together.
