You're right. Three things:

1. He isn't working on this exclusively. In the update notes, he mentions that he's making the game in parallel to a job. He recently finished his degree and sometimes takes time off for his next project. In 2021 he said, 'As I’ve mentioned before, game development is not a full time job for me, it’s just a hobby that consumes a lot of my nights and weekends.' Obviously this must be considered when evaluating the revenue.

2. After he finishes the game, it will still have a long tail of sales over the following years. He can develop another game, whose long tail will overlap with the first one, then with a third game, etc. But I don't know how to estimate these long tails after the first couple of years.

3. It seems to be his first game on Steam.

This is actually a very interesting case. I think he does most things right (though he doesn't seem to do enough marketing on Twitter). I assume that he'll arrive at a place where he has the option to go full-time sooner or later.

Yeah it's definitely one of the better cases here, as with all the devs on this list I just hope he succeeds and can make more games.
