YOU KNOW HOW TO CONTROL THE PLAYER, but press "P" to pause, press "L" to switch in & out of low detail mode, & "I" to enable practice mode. When in practice mode, press "C" to place checkpoints.
READ THIS: IF JUMPER"S 1ST AND 3RD COIN DOESN'T REGISTER TO BE COLLECTED WHILE TAKING THE COIN ROUTE, IT STILL COUNTS AS COLLECTED. When I added a real coin there, the game just crashed. Part of Geometry Dash levels 1-15 by me, & levels 16-22 by busydragon. Each level made by me is also verified by me to see how it feels to be the player. Turbowarp recommended for lower end devices.
