Hell Desert isn't about fun, it's about making you rage endlessly for the entertainment of people watching you.
So are Mario romhacks, IWBTG, and tons of other stuff. I like to play games for fun though. If you're going to make an ULTIMATE RAGE level, make it even harder. Play some lunatic levels, and get a feel for the really sadistic, annoying traps, and make a really hard level. It's lunatic now, but not in a good way. I really wouldn't even want to watch an LP of a level with no save points, it would be too stressful and boring to watch the LPer play through the same parts over and over again.
