That game has an underlyingly deep theme like almost no other.
Be enslaved by a sadistic tyrant or give your all to feed its seductive nemesis who lies deep in the shadows.
The athmosphere and the story, paired with the entities and your role in it all make it feel like some biblical event.
Which it's supposed to be, of course.
Your characters name is Eve.
Gomadi is an anagram for "I am God".
Tanas is an anagram for "Satan".
The true ending means defying and killing both, in other words, not believing in them, but still being a "human" loveful being that doesn't kill anything. The android becomes the new human, and as the first is called Eve. From there on, when the story ends, you can guess she helps the other androids become "human" as well, and teaches them to live, without being controlled by a higher being, deity or whatever.
That's so freaking deep, I love it.
And everything the game offers only helps the immersion of it all.
