Mystery Masters: Psycho Train
This is a fairly short casual point-and-click adventure. The hidden-object scenes and puzzle mini-games represent few challenges, but the carefully hand-drawn graphics beautifully realize the narrative world.
Unfortunately, the story has little meat on its bones, and the ending is especially abrupt. There's no bonus chapter to reveal more.
Though there are longer and more fulfilling games in this genre, I would still give this one a thumbs up. It's both pretty and pleasant.
