#MinervaLabyrinth made it through the Steam review process. I learned that if you flag your game as having mature content of some type, but it's not immediately visible, Valve will ask for a level skip to be able to check it. Had I known that in the first place, I would have provided it. Or maybe I could have just put a severed head on the title screen and they'd say "yep, violence, check!"
Learnings for next time.
