Your comments have been really helpful. I thought about changing some cards actions, especially the bring 2 finches from the sky and the card that sends all the finches to the sky. these can be good and bad things to happen depending on the outcome your looking for. but i thought that before i do that I will finish and add the difficulty variants page to the rules V1.8. I havent tried these out yet, theyre still just ideas.
I hope you can try them out and let me know your thoughts. I may use one of them as the base game if it turns out to be better than the current set up.
