Hello, App Inventor Creators! 
I’m excited to introduce GameRoom, a powerful yet simple extension that makes creating two-player real-time games seamless and fun!
If you've been looking to enhance your apps with multiplayer features, GameRoom is the tool you need. With Firebase integration and easy-to-use blocks, you can focus on designing your game while the extension handles the backend complexities.
Prebuilt Methods: Simplifies tasks like room creation, data synchronization, and role management (host/opponent).
User-Friendly: Designed for beginners and advanced developers alike.
Flexible Use Cases: Perfect for games, quizzes, and interactive challenges.
Why use our extension
This same thing can be done using firebasedb.But when i created a 2 player pong game it took half of the day. Using the extension you can do this in 1 hour
What Can GameRoom Do?
