Yellow Cube - Bridge Puzzle

In this example the player has to create a flat platform to walk across. As things stand this would not work as a puzzle because it is possible to reach the other side without creating a flat platform. If we design a full puzzle around the idea of using yellow cubes to create a flat platform, there needs to be a reason that the player has to move the cubes into a specific position. It could be the player has to get an enemy or an object to the other side. Or there could be a door that opens when the cubes are in the correct position.
