Biwon was not intended to attract people.

gargaj: what a sick level design. ;)

shifter: but that's a better side effect than attracting flies, eh?

Madenmann: it's a free bonus level - they didnt want to include it in the game because it was too hard :D

Hmm,. there are impossible double playing videos on youtube!

I considered Henry's House on the C64 damn near impossible when I was a kid, but that was long ago. I think I got to level 5 at most.

I've never managed to beat Ancient Domains of Mystery, but it's certainly not impossible, just hard for a normal human being.

Shadow of the beast on Amiga was pretty hard.

My favorite was "Return to Genesis":

Impossible to finish but with an interesting engine, specially on ATARI ST.

Not to forget Thrust:
