Good indie games are ignored all the time. I tend to seek out indie games explicitly because I don’t have a huge attraction to most “triple a” style games (I dislike fps, sports, 4x, mmo, puzzle, and sex appeal. So I’m mostly limited to not-Witcher open word rpg. Platformers, roguelikes, metroidvanias, horror survival etc. tend to be indie.) So basically I’m usually stuck with “why doesn’t anyone scream about this game more”. Rain World was like that until Downpour came out, finally some fucking attention to it!
One thing you have to keep in mind is that we're all snowflakes to some degree. And so it can feel unfair when a game that really hits our preferences just doesn't receive as much attention as we think it deserves, but that may not necessarily be because people are unaware of the game, but simply because our preferences are not necessarily widely shared.
It's kind of like how in writing a Dan Brown is always going to be vastly more popular than an e.g. Dostoyevsky. It's simply that one author has much more mass appeal than the other. It can feel like a shame for fans of the latter, but it's the way society has always been and probably always will be.

What is the argument here, that it was very good? That's exactly my point, it was very successful because of how good it was (rather than lucky).
