This is just a little guide for the Tick Tock mission riddle.

Riddle me do, riddle me dee, the final IP comes in a riddle for thee.
The first one is the number of times
"riddle" was uttered in this little rhyme
The second is the number of letters
In total from the walls of fire
(Did you remember them? Well, you better!)
Third may give your brain a tire,
But worry not, for it is not dire.
'Tis the beginning of the end, the end of every place.
'Tis the beginning of eternity, the end of time and space.
The final one is not so tricky.
In fact, I'd say it's quite a quicky.
Excluding this phone, in this little trial,
How many ordeals did I give you (in style?)
Put them together and what do you get?
A reward, that's what! And don't you forget!

Part one: The number of times riddle was uttered in this little rhyme.
This one is pretty simple. If you count the number of times the word "riddle" is in the puzzle, you will find the solution is 4

Part two: The walls of fire
This one requires you to go back to the other nodes and count the total number of letters in the firewalls in trials 1 and 3.
If you look at the firewalls, the solutions are: TICKTOCK and GOESTHECLOCK. Count them up and the answer is 20

Part three: Time and space
This is the trickiest one of the four. It requires you to look carefully at each word.
What letter comes at the beginning of "end" and "eternity?"
What letter comes at the end of "place," "time" and "space?"
The answer of course is e but that's not all.
If you memdumped trial 4, you would find a hint that points you in the right direction.
It asks What place is it in the alphabet?
E is the 5th letter in the alphabet, so the answer to part 3 is 5

Part four: How many ordeals?
Up to this point, you've encountered a few trials. Each node represents a number.
If you count up all the nodes in the trials, you will find the solution, which is 4

Put all these numbers together, and you'll get the final IP.
