Simple! Easy! The rules are simple – if you had a skyscraper floor, what would you put in it? Why would it be special? Etc! 1st person does Floor 1, next Floor 2, and so on!

Floor #
This floor is home to bla bla bla. Why? Because yadda yadda yadda yadda yadda. Also, it has yabber yabber yabber yabber yabber. It also has yeah yeah yeah in it. Nah nah nah.
Floor 1
This floor looks like an ordinary hotel lobby by day. At night the laws of physics become rather malleable.
Floor 824
This floor is a very thin bridge. You have to walk carefully in order to not fall, and it's nighttime. There's pretty city lights that look like they're far away, some boats around, and a deep, dark blue sea below you. It is almost bewitching. Do not look.
Floor 828
This floor is full of spirals and is inspired by Uzumaki. There's all kinds of things deformed into spirals, in many ways, even humans and living beings.
There are 829 buttons. You have to press the correct button to advance to Floor 830. If you press the wrong button, then you'll start back to Floor 1. There is no difference between the correct button and the wrong buttons.
This floor explains the solution to the previous one: "Use a large plank to press all buttons simultaneously. The system first checks for the right answer, then for wrong ones. Thus, when it knows you pressed 828 wrong buttons, you will already be on floor 830, this one."
It's written on a sign.
You can also aquire a free pet budgerigar here.
This floor is filled with all sorts of siege weapons attempting to destroy a massive castle. The trebuchet however is the most popular weapon here due to its ability to toss a 90kg object over 300 metres. Nobody really knows why it received a resurgence of popularity in the first place anyway.
Floor 833
This floor is a dump. Here's where all the deleted messages go, even the unsent ones. You can see the text you didn't send 3 years ago. Regret fills you inside.
This floor has a large well that somehow leads to Undertale's underworld, not floor 833.
People who want to make friends, defeat enemies, find love and decide what they want jump down that well and are never seen again.
They forget that the ultimate place to do those things is their usual life.
~~~
Simple calculations show that if one more person jumps down this well, Asgore will turn into a demigod and ruin our world.
This floor contains extremely sharp spikes on the entirety of the floor which will cause bleeding when touched. There is an invisible pathway which leads to the other side however there are many false paths which leads to dead ends.
Floor 838
This floor is a lounge for all the fictitious ghosts and scary characters. Some jazzy elevator music's playing, everyone's chilled out, some having a drink.
