Very nice

Very nice animation, and a simple, entertaining story. The movement is very realistic. The only thing I noticed that was wrong is that the marmot is moonwalking.

Nice

Nice theme. It seems that you experimented a little with different ways of conveying what your character was experiencing. The style and animation were good and the artwork was fine, except the characters looked very stiff. While the hands moved, the bodies almost never did. Doing little things like shifting the torso a tiny bit to either side as the hands threw things out of the door could help make the figure look more alive.

Decent

The dog looked fine, but the animation was a little jerky. On the whole, a few more frames her and there would have helped the whole thing look a bit more polished.
As for the story, I can't see any reason why the main character should be a dog. If the main character is a talking dog among humans, shouldn't the story reflect that?

Very impressive

The watercolor style makes for a nice experience. Good puzzles as well, I'm looking forward to the next chapter. One glitch I did find is that when the cart race starts, I tried killing Gretel immediately, but the game just kept running without her. A small glitch in an otherwise impressive game.

Very pleasant

Gameplay is simple and not terribly original in itself. What makes up for it is the artistic style. The music, b&w drawing with splashes of color, and the storyline that all work together to make a beautiful experience. I'm glad you didn't try to make the game longer, because it might have become monotonous.
I liked the splashes of color, but was dissapointed that they were not integral to the game, it didn't seem to matter either way. Perhaps vines might have grown which could then be climbed to reach a ledge. I have some other ideas that I'd be happy to share with you if you perhaps intend to create a sequel.
Overall, a nice game that is peaceful and enjoyable.

Potential

Not bad, but a little too easy. All you have to do is move to the edge of the screen and you can avoid forever.
Visually it looks pretty nice, but it could use some variety in color and shapes.
