One of the coolest features in BallSlop is the ability to animate you own mouth drawing. When you chat through the game, it picks up your voice through your mic and based on volume and pickup, it runs through the five frames you've drawn and it looks like the mouth on your sphere is actually moving and reacting as you speak.
Other players on screen view your sphere as if it's talkin to them no matter the angle at which you encounter them. And we have side profile views where other players spheres pop in while they are speaking.
