During January 2025, Ceriocas developed and delivered a new Simon Game mode for the noah-nm/f24-mario-party repository, expanding the game’s content and user engagement options. The feature was implemented in Java using object-oriented programming principles, focusing on a seamless end-to-end user flow from game selection through gameplay to leaderboard integration. Ceriocas designed the system to handle UI rendering, input processing, and winner determination, ensuring a polished and testable experience. The work established a scalable foundation for future minigames and analytics, aligning with product goals and quality standards. No bugs were reported, reflecting careful attention to stability and maintainability.
