You may have already found these, but to save you some time if you haven't had time to look yet, the error optikalcrow found on the d_wood_7 card occurs because <<set $branchB += >> is missing the number that should be added to the $branchB variable.
The full moon header bug might be caused by having a $branchB value <2, as that could simultaneously be less than $branchC and 2, but I'm less sure about that.
Oh, and out of curiosity, did you make this during just the short period since the jam started? No shame if you didn't (I'm strongly considering finishing a game I made plans/art for a few months ago for the jam, personally), but if you did, that's insanely impressive, the game is super fun!
Werewolves are people too!
