The Reisen series catalogues the tale of a small red-headed girl named Jitter, who recently lost her parents to the war (World War II, I think) and wants to go see her grandmother. This is easier said than done, as she is confined to a bunker far away from where her grandma lives. If she wants to make the journey, she'll have to be cunning and resourceful, doing everything from trekking through dark forests to pole-vaulting over deep water to getting guards drunk. This is a series with good points and bad points, like many others. The visuals are relatively unimpressive, the puzzles are okay in the logic department, and pixel-hunting can get annoying, although it gets much more tolerable later in the series. What really makes it worth playing, though, is the story.
