There is another guide but this one goes into more detail for some of the more complicated achievements
My friend Kinito.
Welcome to the Web World.
Welcome to the club!
A world for you.
(if you are struggling with this achievement then just use a minesweeper solver on google)
Wait until Kinito opens the world and when he does keep clicking the fountain until the fish on it fall off
After they fall off then click on the rope in between the trees above the fountain
You will then be taken to the lost land of the web world and get the achievement
After that you need to find 5 files. You need to use the lense app to see the files
This is where I found mine, idk if its the same for everyone
1. Around the middle of the screen
2. Use chapter select and go to the Meet Kinito chapter and check the bottom right (might not appear straight away)
3. In middle left of the screen in the Hide and Seek chapter when Kinito starts pulling over the game
4. At the top of your screen in the chapter ‘Feedback Hub’
5. Do the same steps as you would to get ‘???’ and then check the top left of your screen as you enter the lost land of web world (stay in the lost land for the next step)
Once you have all 5 files go to the lost land of web world
Then one by one drag and drop each file onto the screen, it will play an animation and then turn the file into a text file
Then go to the chapter ‘Permission Granted’ and when you open Command Prompt type in ‘/delete_all’
When it asks for credentials, open credentials.txt and copy the text (without the brackets)
Do that for the rest of the things it asks for
Then when you enter the confirmatory code it will start deleting Kinito and you will get the achievement
Then load up the game and you will see a toy on your screen, just wait a few seconds then close the game
Change your year to 1996 then load up the game, wait a few seconds then close the game
Finally, change your year to 1998 then load up the game, wait a few seconds then close the game
You will then get the achievement
