Solo developer just means they developed the game themselves, not made it all themselves. I'm not sure how you could write what you wrote without that occurring to you.
In that case, please, define "developed the game" for us. Is doing all the programming "developing" the game? Is coming up with the game design and hiring programmers "developing" the game?

Hmm, it didn’t occur to me. Yeah, not sure it’s obvious to many people so was glad for the explanation
FWIW, that was not obvious to me either, and I appreciated the parent comment
Absolutely not obvious to me, especially since I have heard a lot of solo dev stories that insist it was purely a 1-person project. And it’s true in some cases.
