 Redditstuck has a pretty great walkaround on 
page 500 but some of its secrets have a 
less than stellar hint: "Don't think about it too hard."
So, after exploring for a long time (way too long) and not finding a solution anywhere except the official Redditstuck Discord (recently found from my perspective)
I have decided to make some better hints to hopefully guide anyone that is hopelessly lost in the right direction:
(Keys can be found semi-out of the order listed) 
Key #1) Use the power of math for a very grate secret. 
Key #2) Over-explore with Ms. Pickles, make a bet, and then traverse hidden rooms solo. 
Key #3) Decipher the register's code. 
Key #4) Meet new friends in the labyrinth.
Softlock warning Note: 
Key #2 will be unobtainable if you finish Elle's puzzle without finding it beforehand.
(doesn't prevent you from finishing the flash, only prevents getting all the secrets)
