The Hugo Trilogy

Take Hugo through an animated "classic" style adventure, solving puzzles, finding hidden objects and outwitting the maniac hosts of the haunted house to rescue Hugo's sweetheart Penelope. Use the intuitive point & click mouse interface to move around and get Hugo to do your bidding. Just look at what's in store: a vicious dog, a mad professor, hidden passages, vampire bats and much more, all in a gloriously colorful animated cartoon style. And that's just the first game! In games two and three, take part in a huge mystery whodunit (with a few surprise twists and plenty of red-herrings) in an English country cottage and race to save Penelope's life after she is bitten by a vicious tree spider in an Amazonian jungle adventure. Includes all three games: Hugo's House of Horrors, Hugo II: Whodunit? and Hugo III: Jungle of Doom! Gather clues, solve mysteries, and rescue your sweetheart, Penelope, in this classic parser-based adventure game. Features an intuitive point & click mouse interface in addition to the command line interface of the original version.
