originally the sheep suppose to come out of the barn at the start of the day and the wolfs would spawn in during the day out of player sight but i couldn't manage the logic in time for the jam.
and other than that if i were to update the game i would also update the poke to have a penalty for poking sheep by adding something like a "sheep wellbeing" stat and a money system along with upgrades and items you can buy, and with all that if you poke the sheep the wellbeing goes down you gain less money etc. etc.
