Wow, that was rather nice. I especially love how the style is similar to Satina. It's funny how it said "666" and that there was no God. I think actual Satanists don't believe in God. They don't even believe in Satan. This was a good little cartoon, but not great for me.
Doom is always enjoyable. That's an odd phrase to say. The first demon seemed kind of innocent. No wonder the other demons were afraid of Doomguy. 2danimation is common enough to not to need to be a tag.
