Minecraft mission

I have played Minecraft before, but, seeing as how I hadn't picked up the game for years, struggled to work out the basics of crafting and building. In the end, I was able to build a wooden house. I played the game's pocket edition on a tablet, which may have made the game harder to play than on the PC due to the controls. Minecraft is an open-world sandbox game, where anyone can build anything they want, or simply choose to survive monster attacks and such.
