You know geometry dash. You don't need instructions. And yes, this is called "layout circles", I know how stupid the name and uncreative the name is. No need to rub it in my face because it's already been rubbed in enough.
This is easy and I verified it so don't say it's hard. Sure, it may be hard at first, espicially the wave parts. But overall, it really is a harder difficulty. Insane if you must. I just think it morely varies. The start being a harder and the wave being an easy demon to medium demon. Also, this is based of on africa circles. It explains the dash at the end. I don't know how to put an end wall so when you reach the end you win.
