@Kaze_Memaryu Honestly, it does. Isaac is a young boy being raised in a Christian home with a curious, creative mind. This leads him to experiment with a lot of things that are taboo in his religion. You can see in between levels that he crossdresses, and thinks about suicide a lot (perhaps due to the constant bullying he receives in those same intermissions). He also is scared of his own body (sex organ, specifically), as his mother or one of his Christian peers has demonized it.
He fears becoming consumed by these things that are evil in his religion, and it comes out in the form of the grotesque, deformed monsters he combats, as they all typically have something to them that is taboo. They're either obese, naked, sick, filled with parasites, gored, leak some type of body fluid, or resemble a sex organ. Anything not after him was murdered, or committed suicide.
Everything is overdone because he is a child with a big imagination, and even bigger fears. The dungeons he goes through aren't actually real, these are moreso a story he's written of himself struggling to fight that which his religion deems evil, and, at the end, having to accept the fact that he cannot escape them and is therefore evil himself. No matter how much he fights, he is constantly corrupted by items he finds in his journey, attaching to him like leeches.
This isn't spoon-fed to the player, and you have to go out of your way to realize it. That was McMillen's plan all along, and he's admitted to it. He didn't even want anybody to pay attention to the message, as it was solely a release for himself. So if you're not a fan of that, I completely understand. Abstract art isn't for everyone, especially if you can't relate to it.
I hope I don't offend anybody with this post, by the way. I'm not trying to imply Christianity is unhealthy, although it can be and has been to some due to extremists, which every social group contains. Its different for everyone. I'm simply stating the message Edmund was trying to express through his game.
