use the spacebar, up arrow, or w to jump. Dodge the obsticles to get to the end. This is the hardest geometry dash level that is on the full version. Be warrned, it is hard and also very laggy because it is just a prototype. the menu is if you want to use hacks because this was too hard for you. Dont worry. Im fine with you using them. Why did I put them in there in the first place?
