Geometry Dash Congregation lasts 3,4 minutes and contains 23,725 objects. Congregation has sync-based gameplay and challenging timings. Due to its unusual gameplay style and extended pre-drop segment, the level is one of the more contentious levels on the Demonlist.
In the first part of the level, you play mini-cubes very closely. A lot of times, you have to jump over blocks and through very small gaps between spikes. Objects in this area are mostly decorated with blue, and the effect fades so that some blocks are hard to see and need to be remembered. There are also moving sawblades in this area.
After that, this part also has some orb times. This part has the same decorations and also uses the fade effect. A few pieces of decoration are orange, which is a hint that the level will drop.
Tight normal-size ball timings make up the third part of the game. The way you play is the same as in the last part, but there are some flashing red and orange things that you can use as moving platforms.
