40 Winks, known in Japan as Naps (ナップス), is an action-adventure platformer game released for the Nintendo 64 in 1999. Developed by Eurocom and published by GT Interactive, the game follows two siblings, Ruff and Tumble, who must collect forty winks scattered throughout a dream world in order to save the world from an evil tyrant. The game is played from a third-person perspective, with the player controlling Ruff and Tumble as they traverse the dream world. The game features a variety of levels, each with their own unique enemies and obstacles. The player must use Ruff and Tumble's abilities to solve puzzles, defeat enemies, and collect the winks. In addition to the main quest, the game also features several minigames, which can be played alone or with a friend. The minigames include a race, a target shooting game, and a puzzle game. 40 Winks was well-received by critics, who praised its graphics, gameplay, and soundtrack. The game was also praised for its replay value, with some critics noting that the game could easily be played multiple times. Despite its positive reception, the game failed to make a significant impact in the market, and was soon overshadowed by other games.
