The 8 keys of limbo, except they are sentient now, each with different personalities (of course). Key 1 is ‘normal’. Key 2 is energetic. Key 3 is silly and memey Key 4 is irritable. Key 5 is more serious. Key 6 acts cool. Key 7 is trying to figure out what random slang means. Key 8 is crazy. They mix up, and you need to guess the right one to win. Guess wrong and you spontaneously combust.
