Hi! I played your game, it has a good emotional hook. At first I couldn't relate to the main character because it sounded more like a person. I never had the chance to convince myself it was a dog. Maybe if the story had some more background that would help with the illusion.
I dunno if you worked it out but when I ran the game I thought it didn't work because it was black, it didn't do anything until I accidentally clicked the screen. That might be a problem with user experience.
All in all a nice little game :)
