Basically that song is from one of ZUN's albums, so it's not really anyone's. (CtC was a fan-made game)

Original: https://www.youtube.com/watch?v=20oNhpzrCWs

Perdy Piano Version: https://www.youtube.com/watch?v=zHYJsVNfiJw

pretty solid piano ver.: https://www.youtube.com/watch?v=mpSP0e6S9yo

Piano medley: (look in descr for specific song) https://www.youtube.com/watch?v=vUjiys9cSjk

To sum it all up, there aren't much actual remixes of this song in general. Songs from ZUN's CDs are usually not as popular, which sorta sucks, because a lot of his songs are realllyyyy good. Sorry i could only find some piano shiz.
