"Insanely" is a good word. It best describes the status you are when you are stuck for a lot of weeks. The level makes you "insane". That's why "insanely" is a good word. However, "insanely easy" will be too inappropriate, because the level being too easy won't make you "insane".

"considerably" is originated from "List of Levels". "Considerably hard for some", "considerably hard"...
