Simplicity: Quite simple.
Fun: I love this style of gameplay.
Creativity: Entirely unique idea. I haven't seen one like it.
Visuals: Loved the style, although nothing really conveys the robo dog is a dog except the description. I'm not decreasing that for you.
Sound: Wish you could change the volume in game, but otherwise great.
On Topic: It is far more on topic than most of the games I've seen, even if it is more you control than cooperate. 5/5
Side note: you can get stuck on the walls. Just keep walking.
