Ah, so it’s basically just a check on the characters of the key itself. I see. Well I’ll throw a valid key in there since everyone here is so generous and using the Game Hole as it was intended.

And since everyone keeps giving keys, I’m feeling pretty selfish here. I’d better fix that problem.
The Deadly Tower of Monsters (when did I even have this key?):
