I was making my first song, using FL Studio. This is the melody I came up with. I'm having trouble expanding on it, so I decided to publish the melody as a loop. It gives a feel of being in an 8 bit game, then there's a twist in the story and a lot of enemies come at you (hence why I called it "Closing In").
Please contact me if you would like to use this in a project. We can discuss the details.
