To begin the project, the first step is to establish a hypothesis that aligns with the research goal. In this case, we aim to investigate the impact of moving the first gate in the game from level 30 to level 40 on player return after 1 and 7 days. Specifically, we want to determine if this change resulted in an improvement in player retention. In the game, players encounter gates that require them to wait before they can progress or make an in-app purchase as they advance through the levels.
