Dungeon Crawler TV

Inspired by dungeon crawler Dave, but you are the overseer (TV) that constructs the maze and making the runners compete to make it down levels and reach the end. The most important thing is to have an exiting tv show.
Some but not all can make it down.

To start with, show a maze, rather large.
There could be a setting for how many runners to start with.
There should be a decision on how to enter, all runners at once through one stair (chaos at the start), teleported in at random (non boss/shop/safe house) spot. Multiple stairs, over longer time....
Monster density and level caps per floor?
Loot boxes.
Wathers should be able to assist specific runners..

Should all runners start at the next level at the same time or is it just a continuous run down?

The runners needs stats and traits (aggressive, cowardly and so on)

You should be able to see the stats of each runner by hovering.

To start with it should be a top-down view and the runners are just circles moving through the maze.

The Overseer should be able to affect the maze and entice the runners with prices and so on
