This would be a cool and casual game to play but its too short, too simple. I gotta commend you though for the art style and animations. their smooth and appealing but you could've added more into this.
Like for example...Levels. This could not just be only one level right? I mean games on the portal have more content and longevity than this. I would also suggest different modes of gameplay. But anyways I like the style here, delve into this more, add a little bit of everything.
