This improv game is in the following improv game categories:
Divide the stage in a left and a right half. The right part becomes the left
and vice versa, and the division in the middle becomes a `wall`.
Then play a scene with 4 players and only 2 characters. When a player leaves
the stage to the left hand side, his character, played by another player,
should enter from the right.
The character should stay the same, even though it`s played by a different player.
The center of the stage cannot be crossed as it is a wall. As a gimmick one
might decide to make a hole in the wall, but stepping through this hole would
make the character appear at the other side of the `room` - hard to justify...
