THE FORBIDDEN MIRROR
A mysterious mirror , just like any other mirror is giving reflection, but the only difference is that the person on the other side of the mirror can kill you.
Whatever you do or where ever you go, the reflection will replicate your movement. If you both have guns in your hand, use the environment to escape your reflections shooting.
Both sides of the mirror are 99% same, with 1% difference. Use that difference to your advantage to make sure your reflection doesn't kill you.
The enemy moves along with us left, right , front or back. But form the individual perspective the movement is opposite , because of how mirrors work. Hence , the enemy's movement is the inverse of our players movement.
There are some puzzles in the game like using environmental objects to our advantage to kill the enemy. Explosive barrels, landmines, and guns should be used properly.
