Aww, that means a lot to me :3 Thank you very much for playing + taking the time to comment! I'm really glad you enjoyed spending time with Castor :D
As for the music, I'm not 100% certain so I'll have to go check the terms on them, but I think that I'm not allowed to share them outside of the game because they're tracks I've purchased at some point which are allowed for commercial use. A lot of stuff like that usually states that you aren't allowed to upload the tracks anywhere where they can be downloaded as they are >.< I guess because the copyright belongs to the original musical artist, and they're just granting people like me a license to use their stuff in projects. I will try to find out if I'm allowed to share them anyhow!
