It's a pretty flat world with everything you could want to make any redstone circuit and is untouched besides the visible changes where you spawn. I plan to clear every block in the map and make a half slab world where nothing can spawn untill you build them a place. Right now theres a good sized whole to help the game run smoother with all the blocks i added in the chests you'll see. Chests are labled and it's the perfect world to build redstone tutorials and/or test circuits you wish to implement into your normal world to get them working corectly and get the exact dimensions. Just make a new world in the game and name it whatever you like. The name is the one thing that will remain(you can do this multiple times for however many test rooms you want). Then use horizon to replace your desired games with the savedgame dat file. Plug the usb back into the xbox and have fun.
