Chameleon Twist (Jap. チャメレオンツイスト) is a 3D platform video game released for the Nintendo 64 in 1997. Developed by Japanese studio Japan System Supply and published by Japanese publisher Atlus in Japan and by Japanese-American publisher Titus in the United States, it follows the adventures of a chameleon named Dave as he attempts to save his friends from the evil Dr. Warumon. The game is played from an isometric perspective and features a unique control system that uses the Nintendo 64 controller's analog stick to control Dave's tongue. The game consists of seven levels, each with its own unique theme, enemies, and boss. Dave must use his tongue to swing from various objects, such as poles, vines, and even waterfalls, to traverse the levels and defeat enemies. He can also use his tongue to grab items, such as keys and power-ups, which are scattered throughout the levels. The game also includes a two-player mode, in which two players can compete against each other in a variety of mini-games. Chameleon Twist received generally positive reviews upon its release, with critics praising its unique control scheme and colorful visuals. The game has since become a cult classic and is considered an overlooked gem of the Nintendo 64 library.
