Survival mode is going to be added later. Although there is a ripoff add that seems to have everything already, it's called minebuilder. https://market.android.com/details?id=com.br4mmie.minebuilder Also I downloaded this app through opera browser (on my phone) called snappzmarket at http://www.snappzmarket.com/. Basically you can get any game or app you want for free without a root.
