Stereo Madness

Stereo Madness is the first level of both Geometry Dash versions and the first level to be rated "Easy" as of Update 1.9.

This level is commonly recognized as one of the easiest official levels.

Description
Stereo Madness begins with a basic cube sequence featuring spikes and simple jumping patterns. This sequence gradually teaches the player about holding for consecutive jumps and also when to let go after holding; it continues with an introductory sequence of the ship form, which gives the player wide room to fly and learn about the ship mode. The next cube sequence is slightly harder as it has two triple spike sets, which require precise timing.

The level ends after finishing a ship sequence. This also contains the first secret passage encountered in the game, used to obtain a secret coin.

Secret Coins

 * The first secret coin is located at 50% immediately after the first ship sequence. There should be a sequence of four columns, the last two of which have holes in the middles of them. Jump the first three and slide through the hole on the fourth to obtain the coin, then jump back to the main route. Alternatively, you can jump just the first two, slide through the hole on the third and jump twice to obtain the coin and get back to the normal route.
 * The second secret coin is located at 75%, roughly midway through the cube section with the red background. After travelling upon four adjacent thin platforms, jump four times up onto a line of descending blocks which would normally be travelled beneath. To safely collect the coin, jump off the second to last block to avoid a short spike on the last block.
 * The third secret coin is at 98%, oddly situated above the main passage during the final ship sequence. In this final sequence, after avoiding the first roof obstacle, enter a small crevice just before the second roof obstacle. This will be identifiable because it will have large, faded, fake spikes, as opposed to the rows of small, black, real spikes found along the rest of the passage. The screen will shift and turn red to reveal a narrow upper section with very close-contained spikes. There is a safe break about three quarters of the way through, before one last spike section, followed by clearance to the third coin and an alternate finish.
 * Prior to Update 1.9, the third coin was much more difficult to obtain due to the fact that the passage contained spikes on both sides and forced the player to fly in between. The third coin's odd location was due to Update 1.6 and its introduction to secret coins.
