i love survival maps especialy ones with challenges
yeah they are awesome, i LOVE them even more than redstone (and i realy love it)
btw if you wonder if this works after 1.8 it DOES, but theres a bit luck with in the game. for a starter, you need to be in the ocean or deeep underground for a skeleton to spawn. make bone meal. use it on grass. get seeds. you have a farm!
or you can live on rotten flesh. a bit more efficent mabye.
