The price of one game is not a problem for the price of another game. Make better games, or learn to market them better. Silksong's hype is nothing short of a crazy marketing success, and its price is indicative of a dev team that wants people to actually play and enjoy their game.

Also, I think it's been made very clear that people would have been willing to spend more for it. Make a great game, and you'll likely receive the same reception. And sure, charge $30 instead, and people will buy it if your game is good.
