Time Gal
Time Gal, created during the first age of "full motion" style, is an early laser-disc arcade title released in 1985 by Taito in Japan; it was never released in the U.S.). A port for the Sega CD was published overseas by Renovation Products and developed by Wolf Team (with English localization).
The year is 4001. The evil Luda has stolen a time machine and plans to use it to take over the world. The hero, “Time Gal”, AKA Reika, (a skillful and pretty scientist) is on a mission to chase Luda (an evil mastermind) through different time periods, and stop her from assuming control of all history. In this globe-trotting FMV adventure, with anime-styled graphics, she must cross 16 stages that take her from prehistoric times to future realms and even to historical events such as World War II. She must get the time machine back, and save the world!
You watch animations of your heroine while she travels through levels, and overcome obstacles by pushing the correct button at the right moment. You can change directions, jump, shoot, etc., but everything is controlled during the never-ending fluent motion of Reika. At certain points, Reika would call for a "time stop," and the player would be confronted with three choices, only one of which allowed them to continue onward.
The Sega CD version has a "closing credit" sequence that originally did not appear in the arcade version.
The game was also ported to the Pioneer LaserActive in 1995.
