Fun, Too simple
Good graphics, and well put together. It also has a lot of content, and can be a bit addicting if you get into it.
However, the gameplay is too simple, and button mashing can win easy. When I try to play, I sometimes do worse. There are too few of moves, and usually having to go through complex orders to do more moves doesn't rank too high for a game in my book.
It's also quite annoying not to know what side of the other character you're on. I would be trying to block a character, and half the time, he wouldn't turn around, or would block the other way, etc.
Again, it's fun, but the engine of the game needs work. I know you probably won't even see this (6,000+ reviews gets ridiculous :P), but it's also to put up a review for people who haven't seen it before, and want to read something about the game.
