Just finished Shiver: Moonlit Grove and enjoyed it a lot. The third Shiver that I've played, and I bought it because I also liked the first two. It is more like an adventure game than an HOG, although it has the requisite HOG scenes from time to time. It is intricate and thoughtful, lots of innovative uses of inventory, surprising twists of scene, getting captured and escaping, climbing, digging, swimming, building things, breaking down things, etc. It is not a cheery game, you are alone all the time, there is no underlying romance, etc. There is a sense of tension throughout, but not oppressive and you really aren't hurried (or timed). Pretty simple navigation, no mazes, even the mini-games are on the easy side (too easy).
Even though the story line involves werewolves, they aren't a big part of what is happening; just an excuse. So if you are tired of vampires, werewolves and the like, don't steer away from this game on that account. It isn't creepy at all. I played it on the Advanced level, so no sparkles and minimal hints available. Those things are seldom needed in casual games. I give it a big thumb's up for the genre. Oh, and I had no problems or glitches as were mentioned in this thread back in 2013. Maybe the game was "fixed" in the meantime?
When the only tool you have is a hammer, every problem begins to resemble a nail.
