Hi everyone! We've been receiving comments about chatting in-game. We didn't realize that it wasn't introduced to you in-game yet, so that will need to be fixed, but for now, it's Y to all-talk and T to team-talk. Thanks for the feedback! We truly appreciate all the useful feedback, and it's great to see people enjoying the game.
You'll also notice we've added a new gameplay video on our videos page, be sure to check that out if you want to see what a Mageball match looks like!
