For a company/indie group name, how about mechanical gods?
that sounds pretty good. I had a few ideas for a few more minor bosses. The idea was for five (one per level) spirits controlled by The Lord of Death. Maybe different elements for each. And a few others can be some kind of smaller animal. As far as the elemental spirits go, they could be the part of the way to defeat the Lord of Death. Again, just throwing out ideas.
