Hi, I fixed the link to the demo video.
The sounds you hear on the demo are included in the package.
The way it works is, you add the music maker to the game code. Then you can turn it on, and it creates the background track in real time, as your game is running. Turn off the music maker whenever you want.
The instructions are simple, only 700 words.
You can use your own .mp3 files if you want. I include tips on how to do that.
It doesn't export to .mp3. The ambient background is generated in real time, as your game is running.
You can use the music maker and the music it generates in your game completely royalty free in your commercial projects.
Message me if you have any questions.
