Here is my new map, Wandering! I've been working on it for a long time, and I finally focused on a project and completed it. It's in beta because I might? add more.

Playtime: about 15 / 20 minutes (first time)
Versions: 0.16.0+

What do I do with this .mcworld thing?
Extract it using WinRAR or another file viewer and extract it to a folder, then drop it in your minecraftWorlds folder.

P.S. I would really appreciate your commentary.

Also, you might want to turn your difficulty down, since there are TONS of ghasts in the Nether.
If you don't want to start at the beginning again, just turn on cheats and set your spawnpoint.
