A fun and original puzzle game, Heaven and Earth is essentially a collection of three seperate types of puzzles: an original card game, a slightly arcade-ish game called "pendulum," and a collection of intriguing puzzles called "illusions." Although puzzles are available stand-alone, there is a built-in "tournament" called the "pilgrim," which contains the most difficult puzzles of all three types. The card game itself is worth the price of the whole game. Highly recommended!
