Gotta love those sound effects. XD It's a cool idea, though having to click at the bottom of the screen to bark and/or woof doesn't seem like the optimal control. Maybe a shortcut key? Also seems like you can click within the canvas to walk, then move outside it and you'll just keep going. Not that it's a bad thing but usually games don't let you escape like that...
I like the idea. Feels like a lot more could be done with it too.
