I'm mostly an artist and writer, but gdscript is pretty intuitive for me so I can do a bit of programming as well. My computer runs OSX so I can also test compatibility on that system.
Here's a little sample of some of my art; you can see a little of how I do pixel animations in the game on my page, too. (Yes, I know the game itself is bad; yes I will eventually settle down and fix it once I unearth the original files for it.)
If you're interested in working together, feel free to either comment here or PM. :)
