It looks really cute, but with my dingy old laptop the difficulty is too high, I'm not that fast with the button presses and all... and there's something every two steps. Would maybe be more fun with an actual controller. Still, music, art and atmosphere are all consistent and for people with faster fingers and more coordination on the keyboard this is probably easier and fun.
Also something is not quite right when I try to download the windows version, my winrar keeps telling me it can't unpack the file.
