And yet I find it odd that a boxing game, something which I would expect to be rather boring, actually turns out to be an incredibly fun game. Anyway, one particularly neat aspect of the game is that it really doesn't take itself too seriously. Each of the characters in the game shows this. Glass Joe is a complete moron with one win, tons of losses, and simply meant to help you train for the game. Piston Honda is a Japanese fighter who comes at you with his rapid Piston Punches.
Every fighter has their own unique attack and weakness.
Most of the actual game relies heavily on reflexes and learning patterns. Now, you've got to discover other weaknesses. If you press Up, you'll aim for the head. Left and Right dodges, while blocking and ducking are accomplished by pressing down. If you hit an enemy while he's particularly vulnerable, you'll get a star.
