Although nominally a point-and-click adventure story, the Being One franchise includes elements of hidden object games, room escape games, and a little shoot'em'up for variety. Being One: Episode 4 is more of the same. Navigate your way through hidden (and collapsing) tunnels, solve your way past locked doors, and ultimately see what it was all about.
Taken separately, each chapter of Being One has been a little gem of casual gameplay, combining all of the above elements into an interesting, mysterious, serialized tale. Now that tale has come to an end. Was it worth the journey? That is up to the player to decide.
