So I admit this took me far far longer to figure out than it should have.
But I absolutely loved it once I did.
It works just insanely flawlessly (it will probably be even more amazing if the player has a vague sense of rythym ) :D I can not wait to see what you do you with this, but you must do something with it. Way to good to let go. I would recommend a tutorial of some sort to intro the player and go from there.
