Interesting, but... The camera angle give me a headache, to be honest. On the phone, in order for me to see the whole board I have to be zoomed so far out that the game routinely misinterprets my move selection and although there is a confirm option, it has way too many things highlighted at a given time. Some of the moves are also a little confusing. Just when I think diagonal means across the points, it turns out that it's not always the case. The AI also games up on the player.
