Ever since this thread first debuted, my brain has been running a constant tiny background process trying to come up with the best name. I was on the “lockmaze” train for a while but I just thought of a good one in the shower: Key Ring Platformers, or Keyrings for short.
Your player character is essentially a key ring, and all the abilities you collect are the keys that allow you to bypass the various locks the game puts up.
Keyrings baby, guaranteed to be less embarrassing to explain to your significant other!
