I would actually be more critical than Pineapple now, except about 'normal'.
0-1 = easy
2-3 = normal
4-6 = hard
7-15 = Very hard
Or something like that.
I used to play a few lunatic levels, but I've since gone off them. There are still a few I have that I play again from time to time but on the whole I prefer not to go above 'hard' very often, now (soft as a candy-floss hammer). 'Exquisite Knorpse' (1, not 2) and 'Cyborg Juni' (again, only the first one) were a couple of the lunatic levels I found in the archive and liked.
Glad you're enjoying it. I might release a slightly easier version one day, if I ever feel it would get enough attention (not likely, but never mind).
Good luck with the mushrooms; I perhaps went a bit mad there. And sorry about the passage after the throne; it was only after 'Eurydice' that I realised puzzles like that just don't work well.
But personally I love the epic scale of this level, the huge-ness of everything. The temple is enormous, the lighthouse towers, the mines are vast, the pit is incredibly deep... I loved the vastness of it all.
