                                  The level Editor

The Level Editor is a feature in Geometry Dash which allows the player to create their own user levels and share them online with other people. But you need an account to make a level you also need to verify the level before you release it which shows that it’s possible otherwise we wouldn’t know if they beat it or not. The current hardest level ever verified in geometry dash is Acheron an extreme demon level 10 stars verified by Zoink on August 23rd 2022 in 72808 attempts Made by Riot and published by Ryamu. The first ever demon level ever made was demon park is a 1.2 solo Easy Demon created, verified, and published by M2coL (formerly MidM2coL) on October 17, 2013. It is the first Demon level ever created, inspiring the addition of the Demon rating in Update 1.3, and is now considered one of the easiest.

                How all the game modes work

The ship game mode is required for you to hold to fly and release to go down. The ball game mode is introduced in level 9 cycles, tapping once in the ball game mode you will go up and tapping again will make you go back down. The UFO game mode is introduced in level 12 theory of evrything, 

tapping once makes you jump and releasing makes you fall down spamming makes you go up to the ceiling.
