Well made.
Its very well, I didn't find a glitch or anything of that sort whatsoever. The multiplayer runs smooth as butter, along with the chat.
My only complaint, while ingenius at the same time, is in game chatting. Its very easy to not pay attention if someone just so happened to type a message and the cloud floats on by and you not notice it. Other than that, the game is good to go.
I would say maybe implement an actual chat bar, if possible, or something. But agian, it was clever. The whole game is to be honest.
Keep it up!
