Before creating my game, I've created music. Unfortunately, it turned out that the created music does not match the atmosphere of the game I'm working on in any way. :) If you think that the soundtracks might be useful to you, please use it!
Music is under Creative Commons 0 license, but I would really appreciate it if you could mention me or my current project (even better!).
An example of how you might give credit is by putting something like this in the description/credits of your work: "x soundtrack" by Carnotaurus Team. (And preferably a link to the Steam or Twitter if possible!)
