Reverberations combines a silly (but functioning) plot with some fairly old-style gameplay. Room descriptions are sparse, objects are few, NPCs are terse, and the puzzle solutions tend to be very much of the "because the author said so" variety. Fortunately, there are some hints, as well as an available walkthrough, so it's possible to get through without too much frustration -- and a couple of the puzzles do feel pleasingly natural.
As for the story, well, it's not fabulous, and there are times when the game pokes fun at its own implausibility: the main character is a surfer/pizza delivery boy who just sort of stumbles into solving a high-profile mafia case, and has a bit of a romance with the district attorney as well. The events that contribute to this plot are all very thinly developed, too: searching for clues is usually a matter of wandering into the relevant room and noticing the one object there that is remotely interesting. And the DA is much too sketchily drawn to come across as much of a personality.
Reverberations is entertaining if you're looking for a way to kill forty-five minutes or so (more if you don't look at the hints), but it's not likely to stick with you long, either for the story or for the puzzles.
