This is super cute! Good pacing, especially for a WIP. I think I would either:
* have the autoshear be truly auto (no longer requiring positioning) and lean into it being an idle game
OR
* add more mechanics around shearing to keep it more engaging in the end game, eg: perhaps some kind of herding mechanic, or special food or something.
You could also consider doing more with color if that's something that interests you - like maybe you need a certain number of red and yellow sheep to unlock orange, yellow and blue to unlock green.
