The role of the speedrunner is the exact opposite of a game designer. A designer carves a beautiful sculpture out of wood, first chiseling it from a raw block, then rounding off rough edges, ensuring it works from any angle. The speedrunner carefully examines the sculpture from every angle, deeply understanding it, appreciating the design's strengths and weaknesses. Then, having understood it perfectly, they break it over their knee. That's why I love speedrunners.
