It's like this game hates me!
It was my first time playing eden and I was kicking all kinds of ass, and beat mom's heart with 1 red heart and 10 soul hearts remaining. So I thought that I could take on satan. He hit me with his hoof at the same time my tear hit him, and we both died at the same time.
I swear, it's like those explosive leeches are more of a threat than satan himself.
