Super Meat Boy was the original "The Dark Souls of (Insert Genre Here)" and I stand by that. Is it actually that hard? No, it's not. But it's a fucking Heritage Site of those old "Get Gud" game design philosophies. But unlike Dark Souls, or the more recent games in the IP, Super Meat Boy takes it's gameplay and puts a heavy focus on it. It's smooth. So at the very least give it a try.
