Gameplay is surprisingly complex given how easy it is to learn how to play. The wrestlers hold each other automatically. You control your wrestler by moving his foot in 8 basic ways (adjusting length and angle). By combining different positions, you can achive complex series of movements. Your opponent has competent AI, and the matches often evolve into a mesmerizing series of moves and countermoves-- just like in real sumo. The game is perfect for anyone who appreciates ASCII-only games, or games where gameplay shines through simple graphics. Because the game is so unassuming in its elegant simplicity, it may take a while before you realize how deep -- and realistic-- the game really is. Two thumbs up!
