Most difficult levels in existence?

[James]

By the way, about minustwo: I'm attempting to solve H based on the assumption that I is unsolvable...is that correct?

H is technically solvable, but likely unsolvable without computer assistance. I'd aim for G.

I should take another look at this set. ^_^

pi^2.dat #13 (crash and burn)

YES! This level is deceptively complex. I was only able to find a partial solution (and considering the level designer, it may well be a false lead).
