I mentioned this in another topic, but thought I would put it out here as well - On my website I have a download page where I've been putting various things that are all free, and they include a ZIP file with soundtracks that could be used for the project. As of this message there are just two tracks, the first of which was used in the video trailer I put together, but as time goes on more tracks will be added, anyone is welcome to use the tracks for this game or other projects.
I'm also open to constructive criticism, feedback always helps me improve my work.
