Can't help you there. But perhaps someone over in ~gaming might be able to? I don't know much about that territory, but there could be people there lurking about that are involved or know someone involved with game design that might be looking for a soundtrack musician? Just a thought, you could try it?

I also forgot to mention, check this post out for details #473299 and if the idea of renting the Pin space appeals to you feel free to reach out and we can come to some arrangement that helps you get your work out there.

Keep composing, it sounds great and I hope you do get to do a game soundtrack sometime, when you do, I want to hear it!
