This is NOT just a regular ‘find the button’ map! It has different challenges in every level. There are 5 levels, all of them are possible. I’m sure you can do this!
For Windows 10 Edition:
When you have downloaded the world on your computer, you can Left-double click on the file. It will automatically open minecraft and the world will be imported, have fun !
The world file should be on your device, i do not play minecraft on my phone, so i do not know exactly how you can get the world into minecraft. But you can always check the install guides on this website.
