A dream that i once had

it was like this: i was in a street, with giant yellow walls and a streetwalk (i think its called) at the sides and streets in the middle with alot of cars driving. And it was infinitly wide, just that i dont know how to make automatic generation or very big stuff since someone will of course find the end. it was not that scary, but the walls were big, like, very big. how i already mentioned, it was not scary. i tried my best remaking this, since you know, when you try to remake stuff out of memory, it comes out worse. . Please like my game!
