The core gameplay is nice and quite addicting. Loved the sheep art and animation.

Some personal observations:

• Would have loved an option to quit/exit the game.
• There were a few light that were to short and their top was visible.
• You can place the sheep's in the corners and on objects and they would not move from there. Maybe consider to restrict the player from placing the sheep there. I was exploiting this by placing the sheep on a fence and stacking them there, as you can pick them all up in one go.

The graphic and audio is nice. The core gameplay is good and addicting. Overall, I had a great time playing this game.
