Very nice rhythm game.
This was very well done! At times, it felt like things were getting out of rhythm, but after a few more beats, everything went back to normal, so no big complaints there. As for the difficulty... Ironically, on hard mode, the first half of Defcon Zero almost got me but I managed throughout the second half just fine, but Hokages Funeral was surprisingly easy. Just the same thing for each hand, and it didn't even require the space bar.
Here I was just saving it for last because you marked it as the hardest song. I'm thinking that you might have done that because it was the longest, but is just wasn't all that challenging. I haven't lost on any of the songs, so I'm hoping that (if there's a) next time you could either include a more difficult mode, or jazz up the hard difficulty. The two extra modes were interesting, but I'm pretty sure they were there just to confuse, when all I wanted to do was enjoy a rhythm game.
