Mirrors (Test Subject series)

Mirrors are interactive objects in Test Subject Blue. Small pieces of metal attached to the wall hold a piece of glass. The glass can either be pointing left or right, depending on its position. Mirrors are introduced late in Test Subject Blue, but appear a lot throughout the levels. Mirrors will deflect Orange Enzyme Bullets and Blue's Blue Enzyme Bullets, but only these they will deflect.

Mirrors are usually placed so that the Bullet they deflect will be shot into another Mirror, and so on. When first introduced, Mirrors are used for deflecting Orange Enzyme Bullets, and making them travel to places previously unreachable. They are still used for that purpose in other levels of Test Subject Blue, but are later used for puzzle solving.

If an Orange Enzyme Bullet and Blue Enzyme Bullet meet when being deflected, they will simply pass each other. Mirrors will flash white when a Bullet touches the Mirror, along with making a sound.

Trivia

 * The Mirrors in Test Subject Blue bear a strong resemblance to Rotating Mirrors from Canary. Coincidentally, Canary was the game released before Test Subject Blue.
