If you like explosions then mod Stick Explosion
for Minecraft PE 0.12.1 and 0.11.1 you will love. Mod
allows you to craft in the game the stick-srivalo and quickly process large areas, clearing them from unnecessary elements. In addition, if you type a command in chat /SurvivalFly on and /SurvivalFly off you will have the opportunity to fly in survival mode. In order to start using the stick, I advise you to craft more of them, since they are disposable after use in Minecraft PE disappear.
Now you will have more opportunities with the mod Stick Explosion in Pocket Editiobn and you don't have to manually clear the site for future buildings and get the opportunity to fly in survival mode that will be useful. Now playing Minecraft PE
will become even more interesting and fun.
