The way the story branches out...  all the possibilities... ALL THESE ENDINGS !!! This is a Murder-Mystery LABYRINTH and I LOVE IT !  It's full of traps and dead-ends.  And tragedies that can, or will not, be avoided. ;)   Oh, sure, there are fun & sweet moments, but the gasps!  THE DRAMA !!!   Excellent replay value. Now if you'll excuse me, I gotta strategically maneuver my way to another ending.
