Hey thanks for playing! Once you've unlocked all the cows and seen all the CGs there isn't much else to do besides watch your cows walk around the ranch, which I think is kind of cute haha.
We have a fix for the quest log bugs ready and I would like to implement a proper in-game tutorial, but for the spirit of the jam we won't update the game until the voting phase is done.
Your question did make my brain explode with some potential ways we could put an actual ending into the game, so we might be able to add that as well, but I think we plan to keep this about the same size as it is right now (no pun intended >.>)
