Love that you're using the jam to test a team for your bigger eco-focused project. I founded ComposerScout, a free site where indie devs find artists and composers. It's free to be on, and I don't take a cut of anything you pay people. Set up your studio there now and it's ready for the bigger project too. Post the 2D artist role and artists who join get it in their inbox: https://composerscout.com/#studio-edit/role
