I really really enjoyed this game before the update but now (and dont get me wrong i like the ideas and style) the new UI makes me lag, buying anything is slow as dirt and it scrolls erratically in the upgrade menu.
I will keep coming back occasionally but for the first time since release I won't be playing regularly because it just chugs. I really hope things get back around soon. Even the opportunity for us with less than average laptops to have the old UI would be neat.
You have a really cool game though, I am sure it will be just fine.
