I love the graphics and the mod you achieved with the snow! Just walking with the scroll parallax feels great. The animation of the dog is very good, and the dash effect is really cool. I also liked the effect of shooting when you bark from behind, feels very powerfull.
At the beggining the snow looked a bit strange for me, but after playing, I think it has a lot of personality and it gives the game an unique style.
The idea of the bottom text is great, and I think it has potential to tell a good story, I hope you continue with the idea! Congratulations for the game!
PS: Did Insterestellar inspired the song?
PS2: I liked when you barked the human and appears a heart :)
