pretty sure it is, however i recommend to double check with a mod before starting
i'm can't believe it is exist
there isnt a lot of visible evidence that "no sun" even existed, so ill give you the benefit of the doubt on that
i believe there used to be/is a category named "no sun" which is doing the exact thing you described in the beginning post, so this idea isn't very original unfortunately
the second idea you described doesn't seem to be very interesting either
sounds like 100% but you beat the game in the middle of the run instead of the end neat idea though
i can understand the 2nd point, but i think 1000 candies would be a little more interesting since there would be more routing involved
1000 candies - get 1000 candies, they dont have to be unique, timing is same as all unique candies all shop item - self explanatory, get all hats in shop, time ends on last purchase i understand if you dont like lol
ssurt on his way to roast everyone that has ever existed
i don't follow the category extensions at that level of knowledge unfortunately
it would be miles better if you had to enter EVERY sub area or also get the ice creams in them, but as you said, its hard to judge what a sub area truly is
