Assets were all really great and cohesive. Despite it being a very simple mechanic, it was fun and kept me interested longer than I'd expected. If you're not already planning on turning this into a phone game, you could totally do it. The only cons I have are fairly minor, which is that the theme interpretation could be a little stronger and an indicator on the ducks in your circle would be helpful, because it was a little easy to misinterpret if they were inside or not when near the edge.
