I love how the poor guy is suffering. I know that sounds a bit weird, but the animation is so funny and the movement feels awesome. Although the dog's animation is a bit slow for its speed,
if you just added a few dust particles to the dog when walking and made the animation slightly faster combining it with a blend tree to make the trasition smooth it would be just perfect.
The art is amazing, the idea is really original and the game is incredibly fun to play.
Great job! You are a good boy! But that's just my opinion, the poor guy from the game probably disagrees ;P
