Still needs some work
It was definitely an improvement from the first episode. It still needs some work in the writing department. A lot of the time the words said didn't match the subtitles given, or the subtitles had spelling and grammatical errors. This isn't a big deal though, just needs some work.
I see that you are probably trying to do something different with a Samurai theme, but I think this flash would be more interesting if it actually involved Japanese Samurai.
At times the sound effects were too loud to hear the dialogue (hence subtitles I'm sure) but it was just a little distracting.
Also, during the fight scene, the music just seemed completely out of place. It was like I was watching some Dragonball-Z show or something.
I still think it was a good achievement, with a lot of potential!
