This study investigates how linear and nonlinear level designs inspire game flow in cooperative gameplay through a close reading analysis. The research focuses on It Takes Two, a highly successful cooperative game with compelling and unusual combination of game elements that enhance the cooperative experience. Employing a close reading methodology, the study examines the reciprocal relationship between game mechanics and game flow, considering elements such as cooperation mechanics, task structures, and guidance within levels. The analysis utilizes Sweetser and Wyeth's (2005) eight elements of flow to evaluate the game flow in cooperative scenes. By exploring the interaction patterns, mechanics design, and player experiences, the study offers insights into the impact of level design on cooperative gameplay in relationship with flow for designing engaging cooperative experiences. The findings contribute to the understanding of how different level designs shape game flow in cooperative games.
