I finally figured out how to find all of your old submissions, so I could find this one again.
Nicely done song, it definitely sounds like it would go in a boss level. Reminds me of the Obsidian level 6 music in particular (the music for that level was by Doug Hale and it was titled "The Subtegon", if you look in the midi track comments).
But just thinking of having to fight boss robots invading a hospital... if that's what happens :P.
Please contact me if you would like to use this in a project. We can discuss the details.
