Make way to welcome Geometry Dash Robotic Nightmares - an Insane level rated 9 stars by players. ViPriN and Glittershroom - the creator of the game have made it become one of the most hardest level in the series, a real Demon! This time, they concentrate at the difficulty more than the design, in my opinion. Zig-zag tunnel will be seen the most in this part and it's also the toughest path to win. Oh, don't forget the thron wheels in the beginning of the game, they are almost full of the screen if you notice, do not hit them!
There are more to come in this list that you can try anytime, here are they: Geometry Dash Berserk, Geometry Dash Red Observer, Geometry Dash Parastrike
To win this Nightmares, you need to leave the distraction behind and jump over the spikes, blocks no matter they are moving or not
Avoid touching anything and only follow the triangle arrows to go to the right direction
Going through the portals is compulsory because you need to fly in some path and roll in another one depends on the design
Last but not least, good luck!
