There is something quite poetic about the way Minecraft - Pocket Edition has you incrementally building a world, while Mojang incrementally bolts on extras to the game around you.
However, now it seems that the company has pulled out all the stops with the massive 0.9.0 update, bringing the mobile game's feature set far closer to its PC and console cousins.
The most exciting of these changes is that Minecraft - Pocket Edition now features infinite worlds. If you're counting, that's a lot of worlds.
Its not just hills and plains for as far as the eye can see either, because 0.9.0 brings a vast range of new environmental features. These include caves, mine-shafts, lakes, and villages for you to explore, plus new biomes from the PC version.
This should offer endless possibilities for adventurers that want to brave jungles and swamps, while also helping industrious miners to find seams of red stone and onyx.
Wolves have also been loosed upon the game. These wild beasts can be tamed (with a bone from a skeleton as I recall) to join you on your journey.
Mobs' health has been increased, too, and their spawn rate dropped to be more in-line with the PC edition. Creepers' explosive range and spiders' behaviour have also been altered for similar reasons..
You can buy Minecraft - Pocket Edition from the App Store and Google Play for £4.99 / $6.99.
