Plunderland (Universal)

sees you take on the role of Captain Peg Leg's ghost, join a merry band of pirates, and attempt to reclaim your treasure from the unscrupulous sea tyrants that have nicked it.

Along the way, you'll have to overcome a series of fiendish puzzles, interact with various tribes and settlers, and do your very best to defeat huge bosses.

At review, we gave Plunderland a shiny Pocket Gamer Silver Award and called it a "high seas adventure with charm and originality".
