For example, High Hell is under Devolver's account, I'm listed there as an author but it would be really cool to have all my games show up if you look at my project library.

I agree, we need to rework how you can control what games appear on your page. In the meantime you can add the game to a collection on your profile page.

Ah, adding them to a collection that shows up on my profile is a good solution, thanks!
