City Rush is the best simple classic megacollab in Geometry Dash.

there's not much to say other than that it has no flaws and is full of personality. it's actually hard to write a review for a level that I think is perfect, but alas, I will try:

it's a level that excels in personality, is as good as the sum of its parts, and features some of the best gameplay in the game.

it's a very simple level with a simple concept, but because it's so loose, it really lets all the creators shine in their own way. it features a very rare instance of a Lumpy part, which is always a treat—probably my favorite part in the level.

another really cool thing about this level is how it goes from a more modern and abstract style to a more realistic art oriented one as it progresses. it doesn’t come across as forced, rather feeling like a natural result of where each creator landed across the different parts of the level.

the gameplay, like I said, is some of the best in the game. it is very simple but never boring, and it's a blast to play.

all of these factors combined make it a strong contender for #1 on my list of favorite levels of all time. the end screen is super fun too.
