Update 1.6
The 1.6 Update was an update on Geometry Dash that was released on March 25, 2014. It primarily added the levels Electroman Adventures and Clubstep, which was the first demon level in the game.
The update was considered the biggest, until update 1.8. RobTop Games added invisible blocks and spikes along with non colored blocks that the player can penetrate.
Also, RobTop added a few new colors like black and more. Three secret coins were added to each official level. If the player obtained all of the coins, they would be awarded with achievements and icons. Completing the new level, Clubstep, in practice mode would give the player the Black 2 color. If the player completed Electroman Adventures, the other new level, they would earn the Blue 2 color.
