As a game, the concept is cool and the looks are nice - as a rythm-game however, it has a few issues that made it very difficult to play. I didn't feel like the arrows matched up to the beat and I believe part of the reason for that was because it was a bit unclear as to where the hit-point was. At first I assumed it was at the blue arrows at the bottom, because that was the only indication I could see, then I tried to look at where the ground met the background but that didn't seem to match it up either. Also, it was a very difficult song for a rythm-game, since it in large portions didn't use any clear rythm. ;)
I would gladly try it again if there would be a clearer indication of where I'm supposed to click arrows. :D
(Also, I noticed you could get very far in this game by just spamming all arrows, it never seemed to punish you for pressing a button that wasn't supposed to be pressed) ;)
