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.
This floor is literally just doors everywhere all leading to different floors below but one goes to the next floor because otherwise there would be no floor 81
this floor contains several portals to several places, such as Armoria, the Wilderness (from GemCraft games), the kingdom of Linirea (from Kingdom Rush), and a lot other places
This floor represents the 4th of the 7 Sins...Envy. The whole floor is a maze of unparalelled beauty, with lakes of clean water everywhere. The reflection on the water however doesn't show you, only shows you how you want yourself to be...The reflections show you with all you could ever want and you can't get enough of it...until you, following the pools, are driven deeper and deeper into the maze, where the sky darkens, the vines grow thorns, the water shows only a shattered and weak version of yourself and you are trapped forever, with daemonic entities teasing you and laughing at you for being driven away by your own Jealousy.
This floor has a button. It appears to do nothing. Go on, press it. Go on, press it again, again. Yes, good. One more time. Good, good. Another time, please. Continue pressing. Good job, press it again. This might take a while.
This floor contains a massive collection of souls contained within a massive test tube. You can hear the Cries of torment from the souls wanting to pass on to the afterlife.
