IMPORTANT! Right now, only single player mode works reliably. Sorry!
This game is meant to be played as multiplayer. Neither you, nor your opponent will see each other or the ball. But visitors do. They can give you instructions via emojis. But you don't know, whom they're cheering on.
Sadly, this submission did not turn out to be as stable as I hoped for. Therefore, a session must be started first before others can join it. Also, you will likely need someone acting as a visitor.
