Shiver: Vanishing Hitchhiker [Collector's Edition]
A wonderful little point-and-click adventure with a great horror atmosphere, superbly-realized and complementary graphics, music, and sound, and many good hidden-object scenes.
I would not put this in the genre of "casual" point-and-click adventures. First, because it's actually somewhat challenging. The puzzles are all logical and can be solved without a walkthrough, but will require some thought. Second, the horror theme might be too adult for casual gamers: the story is disturbing and there a handful of effective jump scares.
But if you enjoy hidden-object scenes and a touch of horror, this game is a cohesive and gripping treat.
