What makes this so much harder than it needs to be is the way the notes are displayed. Couldn't a simple vertical note arrangement like Guitar Hero/Rock Band have worked? That way telling which key(s) I was supposed to press would be so much easier, because the way it is now I get confused and I can barely last a minute into the song. It's got a good concept, and I like the music and visuals, but the execution of the rhythm mechanic is flawed.
