I am suggesting a new speedrun category called either Randomizer% or Randomizer Any%. This speedrun category would require you end a run using the randomizer mod set to its default settings in the fastest time possible. This would be a cool speedrun because not only is the randomizer incredibly difficult, but you are required to fight every boss in the game and usually go to every area in the game.

Here is the mod for reference: https://spelunky.fyi/mods/m/randomizer/
