Dear Bill,
This little game mechanic is pretty neat and well thought. It brings something new to the table. Level design and execution around it is awesome. You made a perfect setting for this game mechanic and also fitted it into this jam concept. I really liked the simple sheep and dog sprites. Nice little music and good sound effects. Only problem I had with this is the game gets really hard pretty soon :D. Or I didn’t understand some tricks.
Well made!
