Love that you're keeping it beginner friendly and just making something fun. I founded ComposerScout, and you can post the voxel artist, audio, game designer and writer roles there as a hobby project, all on one post. Creators open to hobby projects see those first, and it takes about a minute. It's free to be on, and I don't take a cut of anything you pay people. We'd love to feature your project there: https://composerscout.com/#post
