Most other indies flop because they have dogshit character designs that appeal to no one
You can make a game with bad flintstones animation (literally every doujin game to exist) as long as the tits are big enough or the guy looks like he escaped from Rob Liefeld's basement.
This is why Chaos Code has been having tournaments for 10 years, got multiple re-releases, is on EXA, is on Nesica, and got a sequel despite being a "dead game" in the west.
But when most American indie games are just NIGGA IN A HOODIE or WACKY NOODLE ARM TUMBLR MAN then no one is gonna care enough to even click on it.

Name one person that likes a character from Punch Planet enough to cosplay as them. Show me one person in the world that drew fanart of Area Zero. Point me in the direction of a single nigga that even pretended to do anything regarding Fantasy Strike that was not just a polite nod in a video essay that talked about Strive for 3 hours.
Go ahead, nigga, I'll wait.
