This video shows multiplayer in action on a single screen. The editor is loaded into two separate browsers, and a preview is loaded in each one. On one, we click Create Room, and then we join that same room on the other one, which links them together. We can now play the task as both players, alternating which one acts, and seeing the task from the perspective of both players.
