Hi, thanks for planning to use my music in your game :)
That's absolutely fine about the license.
The restriction is intended to prevent the original audio files from being distributed as standalone assets, such as being included in a separate download, asset pack, music library, or otherwise made directly available to end users.
Audio packaged into the game's normal exported resources is something pretty much expected, so don't worry about that!
Please get in touch if you actually end up using my music, I would love to check and support your game!
