Made a Chess Game with 1k+ Moves from Best Games. Feedback/Improvements?

Hello! I'm a passionate chess enthusiast. I couldn’t find a platform that showcases and allows one to learn the best moves ever played in international matches. I wanted to create a game that does this while being enjoyable, swift, and competitive. Took sometime, but now my game is out on both iOS and Android.

Android: https://play.google.com/store/apps/details?id=com.superhugestudios.chessblitz.chessgame.friends.chess

iOS: https://apps.apple.com/in/app/chess-blitz-multiplayer/id6446757472

As this is my debut project, I'd greatly appreciate suggestions on how I can enhance and make the game better. What features would you like to be added?

Currently, I am using a AI bot to play as the opponent whenever there's a low concurrency, and also added a feature to invite friends to play against. I made a custom algorithm to calculate the ELO scores of the player based on how one plays, and place a puzzle into a particular ELO bucket as well.

I am also looking for people to help maintain a site I built, The Times of Chess (https://thetimesofchess.com/), to populate strategies and best stories around Chess.

Would love to hear from you and get your feedback! If you'd like to join me in developing this game further, do let me know! :)
