One fun fact is that Geometry Dash Infernal Arena is placed 28th among the most popular levels in the Geometry Games series.
The remake of Geometry Dash Meltdown Viking Arena level has 1 minute and 13 seconds and contains 11498 objects. The game begins with a cube stage in which you must hop over saws and spikes. The ship follows, on which you must fly around obstacles. Then the rather simple cube resumes. Then there's a ship that you can just fly into the moving lanes on. The same light cube appears again. The level has passed since you jumped on the trampoline!
The first coin is at the 45% ship stage. You must jump 18% and collect the key to collect it, or rather materialize there.
The second coin is 55% through the cube stage. You don't have to leap on the wall to get it; instead, slide down to a hidden surface.
The third coin represents 70% of the way through the ship stage. It is virtually free to collect.
