You can't have your cake and eat it too.
This is the drawback of a more open marketplace. Those saying you should just vote with your wallets are right -- don't buy the games that look bad. It will discourage "developers" from continuing to pump out garbage if their goal is to make a quick buck. It won't stop those that are doing it "just for the lols", but them's the breaks.
Of course, Nintendo needs to be curating their front page better, and they need to be encouraging better quality devs to release their games there so they don't have to highlight whatever comes out that week just because that's all their is to highlight. Give the bigger or higher profile indie games a reason to come and they will. The eShop is actually a healthy place to release a game.
They need to hire a Dan Adelman replacement ASAP, and let that person actually do some work on the catalog. But without someone steering the ship(shop) they're going to sail just as aimlessly as many of these games are created.
Also, I'm no fan of NintendoLife, but to those who are saying things like "good on the dev for firing back", I don't get your position. It's a site with the mission of reviewing games. If they provided an honest review of a game, it doesn't matter if it's positive or negative, the dev shouldn't be trying to throw them under the bus. Don't create some kind of narrative where the integrity of the review should come into question unless there is proof to back it up. They're free to disagree, but doing so civilly is the way to do it. Then again, you often see this from devs of this style and quality of game, so, I guess it shouldn't be a surprise.
