Oh thanks, that makes sense. Anyway, I think I'd completed more, and I don't know why I felt like it wasn't adding up. I'll play one more time to check.
How does the system count? Is the run complete when you're defeated inside the dungeon? Does entering and exiting add up? It only adds up if you beat your highest previous depth?
In case I can't figure it out, here's my name: Nobuhiiro.
