The development of the Evil Effect: Prologue story is centered on your own decisions. Having total freedom of movement, you will depend on your instinct to find your way out of the sinister place where you are, avoiding death.

You will never know when you will die, since there are turning points in the story that you as a player will be unaware of at all times, thus making it quite a feat to reach the end of the adventure.

It also highlights the fact that it is impossible to see all the content of the game, in the same game. Well, the environment also varies depending on your actions.
