It wasn't just COVID fatigue that stopped that campaign dead in its tracks. If I were to run another Greek-themed adventure, I'd want to use Theros instead. (I wish WotC had published more than just the brief 1st-level intro adventure.)
Thanks! And yay, someone got the reference! I think I must have been playing Wii Mario with my kids when I first came up with the idea.
One player has given me their feedback:
"Hmm not sure of my favourite floor. I enjoyed the early one where we had the TPK. And I liked the Githyanki one just because it was so challenging. Least favourite I think the mindflayers simply because they were a bit of a let down. They are my BBEG. I really liked Rex as the nemesis. didn’t really dislike any NPC."
