Puzzle Analysis

For my puzzle analysis, I chose Portal 2's Test Chamber 3.
The main mechanics of Portal 2 is running, jumping, shooting, and picking up objects.

When you first start the level you see this

The player immediately knows where to go because of the shining icon on the door.

When you go up the stairs you see another door, a large button, a portal, a cube dispenser, and a path showing you where to go.

When you walk over to the dispenser, a cube falls out. You then shoot a blue portal under it to launch it out of the orange portal. Then you pick up the cube and place it on the button. 

Placing the cube on the button changes the cube highlight and the pathway to yellow. It also opens the door and shows a little checkmark next to it. 

This puzzle makes the player feel smart by showing them where they need to go, but not telling them exactly what they need to do. 

This level is a very simple ordinary use of an object puzzle.
