I think it looks cool. But, while the buttons appearing to the music looks great the first time, I think it would be very annoying in an actual game. So, an option to turn that off in favour of the menu appearing instantly would likely be much appreciated by players.
It's very good! I only have one problem: the map. And if these aren't what I think they are that's fine, but the Calm Belts (those strips of light blue) should be going from North to South. I know this is only the first version. I just thought I point that out.
