Lovely foundation for something very professional. The artstyle is excellent and has a nice, illustrated quality, and the directional and idle animations make the dog's movement flow well. Layering the canopy of the trees could be an idea to provide an effect that gives depth to these illustrations. As the game page says, there's not a lot to see and do yet, but the care and attention to detail, and the work behind the intro sequence, shows such promise for a first game. I really hope you're able to do something with this!
