Overall, your idea is great; love the bouncing sheep and the idea of using both the shepherd and the dog to corral the sheep. (Got 13 into the pen!)
There are a few things I'd recommend improving for a revisit, or for future projects:
The controls are a bit much to take in initially, but I eventually got into the flow of using WASD/arrows simultaneously, and slightly adjusting the camera orientation. A point-and-click control scheme for controlling the dog and rotating the camera when right click is held might be better in this case, as your hand is already on the mouse.
Additionally, you can consider using Cinemachine for camera dolly tracks when on the road to auto-orient the camera, then transitioning to a player-controlled camera when off the road.
A few more minor things would involve some juice and UI cohesion with the world's aesthetics, but I know time is limited. ;)
Finally, nice art, sounds and music! They fit with the gameplay and mood this game evokes.
Nice entry, best of luck!
