I tried NG on my wife's iPad 2 and I have to say I was surprised that it was running a lot better than in the past. Even on high settings the animations decently smooth overall. I haven't even optimized all of the animations, so I can see it being even better. Just thought I'd mention since mobile performance has been known to be pretty abysmal. Things are gettin' better.

Does it work for android at all?

It works on my tab 3 but the ames resolution doesnt fit right on the screen.

Yeah, the game was primarily designed for people to play on laptops and desktops. Mobile platform was really an afterthought. There's so much that depends on hover and larger screen sizes.
