I won't go into detail about it here, I would say what you need for a better multiplayer experience based on my little or a lot of experience, I hope it helps 
-Option to modify the waiting time between players: The games sometimes go on for too long because there is no time limit for each player's turn. I think it would be much more practical to be able to decide how much time each turn has to speed up the games. It would be fun to have games where you only have 30 seconds to make your moves.
-a general in-game chat: It can get a little boring waiting after dying. It would be nice to have a chat to pass the time while waiting. A general chat would add a lot of extra to the games, especially for lone wolves.
-can you write the code of the rooms: Sometimes it doesn't let you paste the room code. I think it can be fixed by leaving the option to enter it manually.
-EXTRAS
This section is what I consider not essential to add but it is not bad to comment on them since we are
-have a spectator mode: I think I would give the option to spectate, of course it would be an option to activate because there could be problems in the aspect of telling the other what one does, although it could be solved by making the spectator only able to have one chat apart from the general one.
-radio: It would be cool to be able to choose the music you want from the various compositions that the game has, something like what Payday does when you go to do a raid, letting you choose your raid music, although here everyone would hear it.
And I think that would be all, I hope I got something right and there is nothing left to do but continue enjoying such a good game.
