like idk what number to choose for easy, medium demons etc.

just ignore, it is website's least useful feature

none, i dont use it

0 if i don't like the difficulty and 100 if I like it

roll a d100 die

i add 10 for every level of demon or i pick a random number

I just ignore it, rating difficulty on a scale of 1 to 100 is so unbelievably arbitrary it may as well not exist

Just slide it randomly. No clue how it works.

I sort through the existing average ratings and find a spot that I think a given level fits between, e. g. I built a level is harder than Hungry Humphrey but easier than Speed Racer, so I gave it a 12. Won't rate something or in reference to something if I haven't at least played it enough to get a sense of its difficulty, of course (some of y'all need to pay attention to this).

I understand why there aren't any guidelines for difficulty ratings (or at least I can imagine a couple reasons), but I do feel like some sort of basic reference should exist because right now it's very all over the place.

I came up with my own system back when I first started doing level reviews a couple years ago. My basic idea was to start with 10 notches for each in-game difficulty tier, and then kinda adjusting it to give more room for extremes and less room for easy and normal levels to account for those having different variation in difficulty. I know that all sounds very formal, but it didn't feel like it; I basically just wrote everything down on a handheld whiteboard until I was satisfied.

I personally like having the difficulty slider, since it lets us indicate what we think about a level's difficulty, but it probably wouldn't hurt to give it a little more in the way of standardization.
