Developed and integrated a Rock Paper Scissors minigame into the noah-nm/f24-mario-party repository, focusing on core gameplay logic, gamepad input handling, and a tournament-style progression system. The implementation included seamless integration with the game selection menu and a post-game leaderboard flow, enhancing the overall in-game experience and supporting competitive play. Utilized Java and object-oriented programming principles to ensure maintainable and readable code. Targeted code cleanup and the removal of verbose logging improved performance and maintainability. The work extended session duration and player engagement by providing a cohesive, interactive minigame experience within the broader game development project.
