Citadel of Buttons

What is the Citadel of Buttons?
The Citadel of Buttons, or CoB for short, is a intense difficulty ascension-based citadel in Baseplate 1. It's the first citadel ever made as well as the first collab tower. CoB was made by JaykPog, and superultranoob300, the owner of STACKS. This is also a Lore Citadel, meaning it contains a certain entity that had built the citadel specifically for the player. The main communication for the entity is signs.

Trivia
= CoB has extremely, EXTREMELY inconsistent design and creativity. This is mostly due to JaykPog and superultranoob300 having extremely different building styles.

= JaykPog put WAY too much effort into this citadel, despite the point of STACKS being to put as little effort into your tower as possible.

= This citadel by far is the most inconsistent tower in game. Floors made by superultranoob300 end up being in the Hard - Difficult range where floors made by JaykPog end up being Challenging - very low Remorseless

= superultranoob300 spent a good hour on the floor 1 puzzle

= superultranoob300 complains about JaykPog's floors because "THEY'RE TARTARUS DIFFICULTY!"

= superultranoob300 actually plays Professor Layton and the Curious Village and is why he put in some music from the franchise

= The CoB rooms to get to the portal are canonically called “CoB Trials”

= There is a secret behind the creator hint saying “By: Exosauce”

= In the CoB Trials, there are 3 signs that'll say "Exosus: Good riddance, child."

= This holds its own winroom because Super thinks it’s cool to make 3 or more winrooms in a baseplate

Continuing from here
GG! You just beat CoB, good job beating the first citadel in game! Anyways, now that you've beaten this tower you can move on to some of the Psychologically Unsafe Towers, as CoB is most likely harder than the other towers in the advanced category. If you haven't though, make sure you've done all the Advanced and below towers.
