Multiplayer Tetris with Symfony UX + Mercure

[sblondeau]

I built a multiplayer 🎮 Tetris clone using only Symfony UX, with Mercure handling real-time synchronization.
You can try the game directly at https://tetris.sylvainblondeau.dev/.

✨ Achievements:

• A fully functional single-player mode
• A multiplayer mode (2 players) where completed lines are sent to the other player 🔥
• Playable on desktop or mobile

🛠️ Main challenges:

• Managing the game loop with data-poll (speed increases with levels)
• Handling keyboard events (arrows to move and Q/D to rotate)
• Tetrominos rotation algorithm (can still be improved 😅)
• Overall performance (lag at high speeds 🐢)
• Mercure deployment (fun times! 😆)

This short 🎥 video sums up the key features.
