Very neat game! I found the dynamic between Anubis and Seth quite interesting. Though at times I was lost as there were terms I don't know (I don't know much about Egyptian mythology, sadly!) I know that given the limitations of o2a2 adding something like a glossary would likely not be possible, so for what it's worth, I still enjoyed it a lot!
The art is beautiful and I really love Seth's eyes especially! I also found the way you describe what different areas of the body / face do quite interesting.
Will be fun to see what more you do with these characters!
