You will create a game in the GB Studio engine based on the simple idea of going to the store. Designers are challenged to think about different levels of goals (long-term: what are you ultimately buying, vs short-term: what steps must you take first to accomplish the longer goal?), the pacing of puzzles or different challenges, and the layout of their game worlds (is it linear? Do you meander and backtrack? Do you become acquainted with a place via multiple visits?) You should also think about how such a simple errand might play out and build an interesting game story. Does the errand bring up painful memories? Are there rude shoppers? Do you fight someone for the last of an item? Do you get abducted by aliens?!
