TubeTwist
TubeTwist is a computer puzzle game created by American studio 21-6 Productions, based on similar classic games that involve manipulating the movement of balls through a labyrinth of tubes, which are utilized to construct a Rube Goldberg style device. The game has a background storyline broken consisting of five chapters, with each chapter corresponding to a different area. Synopsis. The player plays the role of a scientist searching for their missing Professor Jaymour whilst re-assembling TubeTwist experiments to unlock the professor's secrets. In so doing, they must also guide balls of energy known as "macrotons", which  must be guided from Injector Tubes to Reactor Tubes. Three types of macrotons exist: green, blue, and exploding. The green and blue macrotons must reach the reactor of the same color to release the energy from the former. Exploding macrotons are used to clear paths for the green and blue macrotons. After completing all the experiments in a chapter, the story will continue and the player will get closer to finding the missing Professor Jaymour. Development. TubeTwist, along with its story element, was originally conceived and developed by Keith Johnston and Mike Panico of Pinoli Software, who partnered with 21 -6 Productions to assist in producing the game. The final core team to create the game, along with Johnston and Panico as game designers, was Justin Mette as executive producer, Dave Calabrese as artist/scripter/storywriter, Mike Panico in further roles as texture artist, environment designer and modeler, Chris Brethren as level artist, and Matt Sayre as the game composer who created the audio and music to the game. Game updates and special editions. On December 6, 2006 the 'Quantum-Flux Edition' of TubeTwist was officially released. This new edition officially adds support for Experiment Packs, ships with 2 built -in experiment packs, adds the ability to have up to 13 individual player profiles, performance enhancements, and various other small additions, and can import saved data from the original TubeTwist.
