this is my second map i hope you like it i will make more in the future stay tuned please leave me suggestions in comments and thoughts about this map i hope you like it

EDIT:I know this has been converted to a Firefox file and you can't open in Minecraft in that case PLEASE READ THE FOLLOWING.

if you go to files and right click and hover over "open with" and click "Minecraft" that will bring you to Minecraft and you should see the world in your "worlds list".
Hope this helps:)
