Geometry Dash Next Yesterday is an Easy Demon level created by ILRELL, G4lvatron and many other collaborators. As a result, you will observe the existence of numerous distinct spaces throughout the game, each of which was created by a single individual. The player may occasionally experience constant change, which can be overwhelming.
If you want to win, get used to that. The characteristics of each stage account for the abrupt change in speed. For instance, the player cannot move quickly in a water environment, so the game speed is slowed down at that point. The character's movement speed is the exact opposite of space when they are in a different environment, or both speed up when they reach the climax. When actually taking part in this game, you will experience all of those things firsthand. Each author creates a section that embodies their writing style; while they may appear to be out of place, when put together, they give this version its own distinct personality.
Let's look around and feel!
