Minecraft is one of those endlessly updated games as the developers tweak, tuck and expand. The mobile version is getting a hefty update with the developers blog saying:
The plan now is to start digging into making Minecraft – Pocket Edition with Survival features!! Please note that we will NOT replicate Minecraft and try to bring all the features that are already out. This is not possible and does not match the touch platform. I’m trying to be as detailed as possible to show you why some stuff may take some time.
This is what the plan looks like right now and being worked on:
A new file system – to make sure we can support items and mobs in the world
Item system – to be able to pick up items
Crafting – we know you want this :) This will probably need some iterations since the interface will be customized for the touch devices
Mobs – animals and enemies!
Optimizing rendering code – we are experimenting with caves but need to make it work better before we are able to release it
Clean up of code and overall optimization
