Very interesting and crisp, gameplay-wise. I don't recall encountering such a thing as a "melee shoot'em up" where you get, er, up close and personal with a sword slash. It was very fun to use, and i like the little detail of having it slash left then right, instead of always in the same direction. It's the kind of little things that many games wouldn't care about but that makes me tick here.
Nice music, although the backbeat disappears from time to time, making it hard to keep the beat (although in your defence there IS another music playing in my background right now on a different beat so it mustn't help). Also, some enemy shots are slightly offset from the beat, is that on purpose to disrupt the player's rythm ? Nice touch (it disappears in the boss fight though, doesn't it ?)
Overall good concept that is well executed, i like this and will likely replay it again !
