The game _Spelunky_ definitely has the "holy crap this is hard why am I still playing this is it three A.M. already just one more try" nature to it, kinda like _The Binding of Isaac_ does.
That having been said, both games have one flaw that really irks me. I'll phrase it like this:
Any game mechanic that can be circumvented by cranking up one's display gamma or brightness is _not_ a reasonable game mechanic.
