Muramasa is a beautiful game, and despite some shallow issues, you will have a very fun time playing it.
As I mentioned previously, the game has two characters which are two different stories and each one has it's own unique levels boss fights and swords which is enough difference to make you want to beat both character's stories. There's over one-hundred swords in the game which each have their own unique abilities except there's a few which just have stronger versions of previous sword's abilities. The stories of the characters are intriguing and have good endings but they are told rather clumsily with confusing dialog at times and the constant naming of long Japanese names that become too hard to keep track of.
The game is played traveling to different provinces by foot through many different landscapes, cutting up enemies you run into to reach a plot "dungeon" in which there is a boss at the end. This is pretty much all there is to the game besides collecting swords, visiting shops and completing challenging enemy lairs. But getting out your sword and cutting up enemies and using your sword's unique abilities is undeniably satisfying and it certainly didn't get old for me for the around 25 hours I spent playing the game. The boss fights are very fun and challenging and you really have to watch the boss' attack patterns if you want to attack it without it pulverizing you back.
You can hold three swords at once which you can switch between by pressing a button that varies depending on which controller you use. You can use a wii remote, a wii remote with a nunchuk, a classic controller or a gamecube controller (I reccomend the classic controller since you'll be wanting to use a D-Pad most likely.) Attacking in all it's forms and blocking is is all done with one button and another button is used for executing your current sword's special attack. Items can be used by going into the menu or by pressing yet another button on your controller. Sadly, on no controller can you assign jumping to a button, jumping is done by tapping up on your d-pad or analog stick but it works well most of the time.
Gameplay: 8/10
A bit shallow, it could use more RPG elements to make it a deeper game. But cutting up enemies is extremely fun and satisfying and so is watching you're special attack destroy them further.
Graphics: 9.5/10
Without a doubt, the most beautiful looking 2D game I have ever seen. You'll find yourself stopping from your enemy slicing at times just to look at the breath-taking environments. It's kind of a shame they repeat a bit too often at times.
Sound/Music: 9.5/10
The game's music is just as good as the environments, it's a truly masterful soundtrack. I haven't heard such great musical scores in a video game for a while. But like the environments, some of the songs repeat a bit too often. The Japanese only voice acting takes time to get used to but it actually suits the game really well.
Controls: 8.5/10
Combat is pretty much only assigned to two buttons but in the end it works extremely well and I would have it no other way. I don't know about the other controllers since I didn't use them but the classic controller works great for the game. It's a shame there's no way to button jump as on the classic controller, "a" could've worked fine. Tapping is okay though. No motion controls was a smart move.
Overall: 8.5/10
If you're a fan of action games or action RPG's you have to pick this game up and I guarantee you will have fun. It's lengthy with both stories combined, just the right difficulty and a whole lot of fun.
