In this game, you and an opponent are tied to opposite poles and required to battle each other. You have around seven abilities or powers, and your opponent has some preset attacks.
You have to figure what order to combine your attacks, as well as when to wait for an advantage. It becomes an optimization puzzle, where you frequently restart. Some have said that they thought it through logically and reduced the number of repeats.
The writing is beautiful and evocative, and reminds me of Magic:The Gathering. Giant collosi, swarms of bugs, whispered madness.
For fans of strategy-based combat.
