You might consider looking at the stories from the devs behind Balatro and Ballionaire:

Balatro: How a Solo Developer Sold more than 1M Copies in One Month - https://news.ycombinator.com/item?id=47612430

Show HN: I got laid off from Meta and created a minor hit on Steam - https://news.ycombinator.com/item?id=43186406

That is so cool, I know both games but I never knew they posted their stories on here. It seems the first link points to this question though, do you have the correct one? If not, I'll just try to look for it myself
