Maniac Mansion: Day of the Tentacle

Day of the Tentacle is a point-and-click adventure game and a sequel to Maniac Mansion. The player controls Bernard, and later also Hoagie and Laverne, being able to switch between them at any time. By using the commands at the bottom of the screen, the character can pick up items, use them on other things, talk to people and more. Any of the three friends can also send his items across time to another friend.

The game takes place in the same area, but in three different eras, and thus affecting history takes a vital part in some puzzles. For instance, Hoagie can hide an item in the 18th century, and Laverne discovers it in the 23rd century - but by then, the item may have been affected by time and changed its properties.
