Echoplex is a minimalist puzzle game in which you have to compete with yourself. The main goal is to get out of the room in order to move to the next level. While solving the puzzle, you will interact with mechanisms or switches, but you will be hunted by your own shadow, which repeats all your actions. If you open the door, the shadow will close it after a few seconds; if you turn on the switch, the influence of the shadow will turn it off. And if you let the echo get close, you will die.
