FlappyMo, a multiplayer, squirrel-themed adaptation of the classic game Flappy Bird, was developed using Momento to enable real-time competition among players. The game incorporates various technical features, such as player tracking, session synchronization, and remote start functions, to enhance the multiplayer experience. Authentication is handled through temporary tokens, allowing players to be uniquely identified and participate in synchronized gameplay. The use of Momento Cache and Topics facilitates real-time updates on player movements and game conditions, ensuring seamless interaction across all players' screens. The game architecture benefits from server-side and client-side integration, making development efficient and enabling features like randomized game settings for each round. Built with Next.js and Node.js, FlappyMo offers an engaging, though challenging, gaming experience, with source code available on GitHub for further exploration and modification. Momento's resources streamline this development process, supporting features like in-game chat and leaderboards, and offering cross-platform compatibility for a broader gaming audience.
