Jack Hurst created a production log documenting his process for designing the background and first street for his endless runner demo level video game. He began by planning out different gameplay options and choosing for the character to fall down a hole and trigger a "game over" screen. He then calculated the number of frames and pixels needed to animate 20 seconds of running across 2.5 streets. Next, he created a gradient background and layers for foreground and background buildings. Different colors were used on each layer to create depth. Guides were used to help align elements consistently. Overall, the production log detailed Jack's planning, design, and layering approach for the demo level background.
