Her Story--I'm Intrigued

A new game that has popped up on my radar is a police procedural called Her Story.  At first glance it seems pretty silly--you watch videos...of the same lady?--but apparently it's much deeper than that.  You get to play the role of a detective and use your analysis skills and tools to try to piece together what happened.  Here's the trailer:

It keeps popping up on my Steam feed and I've read some really good things about it.  For a little over $5 I could unravel a fictional murder mystery.  I'm hesitant because it really seems like the kind of thing you play once and that's it.  Is a $5 game sufficiently cheap for one go round?

This seems like such a simple but interesting concept.  I thought Papers, Please sounded pretty weird before I bought it, but it actually turned out to be a great game.  Do I take the indie dive or not?
