Great follow up to the original. The game is really polished, the new graphics and animations are stellar! Love the attention to detail.
I think the screen wrapping is really cool, but it took me a while to utilize it to my advantage, the first couple of rounds it didn't feel that nice that you lost control outside of the box. But once I got the hang of it, it added some nice strategic depth to the gameplay.
I don't really see the theme that clearly, but I love playing it regardless.
