I do have a friend in mind who has been open to the idea so we'll see how things go, might be a fun experience.

Awesome!

One thing I would suggest. Take your idea from "an idea for an audio game" and turn it into a detailed, written design document. There are 500 decisions that need to be made even for the simplest game idea, and defining them is 98% of game design. That'll also make it much easier for your programmer friend to do what you have in mind. and in the process of writing it, you'll uncover a host of these sorts of issues and be forced to spell them out.

Let us know how things go!

Cool! Thanks for the advice, it's definitely something I'd like to do eventually so hopefully when some more details surface I can share the experience ;)
