If you have the game, you know about the speed issue. Version 1.1 has been released and the description says "speed optimization". Hopefully this isn't some old patch as the app store constantly prompts me to download old updates. But iTunes says the current version is 1.0. Honestly, I hate the update system sometimes. I download 4 'new' updates, then I get prompted to download them again immediately after! So I dl just the LUX update, then I get prompted to download the old update! Makes absolutely no sense.
