Stereo Madness (Geometry Dash)

Stereo Madness is a course from the video game Geometry Dash. It has a difficulty of easy, and takes (with no failure in between, without practice mode) 89 seconds to complete. 
The average sequence is, a cube sequence as a starter, with just a normal half time, and the other three parts take ~16% each, and go look at the infobox. 
The first SECRET COIN (star coin) is located next to after the first ship sequence. There is a gap, and you have ~3 seconds to think fast before you either die, get it, or lose the chance. 
The 2nd one is located at another place, in the cube form. Look for the coin on the roof, but avoid the spike that guards it (it doesn’t have any special features except point, so feel free to jump).
