A little adventure map funny and funny

This is just a little maze I built in my spare time. It's also the first world I've ever built in Minecraft, ever, so any tips or pointers would be gladly appreciated, and if I'm doing anything wrong go ahead and tell me.

Please download. this house is a tree house. it was made in survival. the picture is the view of the top if you spawn in a tnt explosion just go towards the tall lookout. there will be updates. by grantharvie!!! Antman855's friend.

i don't know but you need to defend the villagers

My first world.
