Tetris game built with React Hooks (MERNG). I created the game with the YT tutorial of @Weibenfalk. My contribution: 1. Server-side (registering users, login, logout, storing users' scores), 2. Tetris theme song, 3. Leaderboard, 4. My Scores (user's scores & levels), 5. Flash alert when a user beats the highest score on the Leaderboard, 6. MenuBar.
