The soup is there!! Since the theme was the artwork by Andy Warhol, I had all the hipsters reference his pop art movement or him directly with one of the hipsters occasionally talking about the soup artwork specifically. I also thought it would be fun to juxtapose the pretentiousness often associated with pop artists and the silliness of MS paint users by having the hipster Andy Warhol fans trying to close the game.
Also, spamming is a good solution for the first 100 or so! However, I built in logic to make spamming less effective the farther along you get. Hipsters run super fast sometimes or on just a couple quadrants before running around the edge to dodge anyone spamming the top right quadrant. I've yet to see anyone get above 300 by spamming...
Glad you liked the game!
