This was one of the things that disappointed me a bit, as I thought that the surface at night would have looked so pretty with the Skyward Sword art style. I wish you could've obtained one of the lights that the knights who fly at night apparently have with them to see, since evidently that would have fixed the problem. I just think it would've been nice to explore at night; the music could've been quieter, enemies could've been different, perhaps there could have been special things to only happen at night... it just seemed like a waste that something that could potentially be so pretty and fun didn't happen.
