>"Nick: It wasn’t quite working, like people would start typing and we’d notice, they’d start typing one character and all of a sudden eight characters appear, it’s all crazy.

So we started using Firebase a couple of months ago." So from that i infer that they were somehow using it to implement the Multiplayer mode. I still haven't entirely understood how firebase is a client-side DB so i am not sure how they were doing that
