Ok I played SW1 and i must say, it was awesome, this one is better, but, it LAGS too munch, I consider it should be the first think you fix, maybe add the option to low the quality at least.
The chaos needing to be buyed to play it´s ... well i guess that good for you isn't, but I think that when you implement the campaing, you should make them playable (only in campaing) that way we could test it, and see if is worth it, but in any case, try making the screen smaller (although, people with the screen being too small could just eliminate every bar, that's right even the navigator, menus, etc, I didn't have any troubles in there.
Well making it short, LAGS, it NEED to be fixed, put some "settings" options at least.
Overall good game, with potential.
