Perhaps the most satisfying part of the game is setting up the multi-hit combos. When you pull one of these off, your character attacks your opponent's character, complete with the sound effects from the original fighting games.
Unfortunately, I discovered a serious flaw in the game after a few days of play. The best strategy is not to intelligently place and rotate gems. It actually works better if you just drop them as quickly as possible and let the great god Chaos sort them out.
