Sentinel: Descendants in Time (2004)

In this quest for riches and knowledge, you can uncover the mystery behind the Tastan Caverns. As you begin your dangerous journey, you'll encounter a female sentinel programmed to guard the sacred caverns. Her dark purpose, however, may impede your progress through more than 20 puzzles. A built-in hint system may come in especially handy as the puzzles become more challenging. Each of the game's eight worlds features diverse environments, ranging from snowcapped mountains to active volcanoes.
