The art and music of this are really good! Each song is a definite bop.
Will say, I think the only bit of feedback I have would be to just have some more visible and/or even some auditory feedback for when notes are hit. Would be nice to see the arrows flash or explode or something, similar to what they have in Guitar Hero. As of right now, they just delete, which is still very helpful, however, I think I mix them up with the notes that are just right after it. Get a lil' jambled.
Regardless, super polished rhythm game you got and great submission!
