Yes, that's exactly how I play, I am intimately familiar with roguelikes and how they work. I've completed the "More Mystery Dungeon" in Torneko: The Last Hope. I have every achievement in Binding of Isaac. I love challenge games with rewarding mechanics. I recently finished Oath in Felghana AND its boss rush on Nightmare Mode. So the whole "it's your fault" or even worse, "you suck at the game," can only go so far. Most Spelunky experts will even cop to the fact that it took "hundreds" of deaths until their first victory. It's really not a learning curve as much as much as repeating the game until everything falls in place for you to squeak in the "perfect run" it requires to finish (and that's not even counting the requirements to get into the hell area).
The difference between standard roguelikes (and even something like Binding of Isaac) is that you're afforded some semblance of margin of error. Every tiny, micro mistake you make in Spelunky, especially after the mines areas is pretty much instant death. And if THAT wasn't instant death, it'll kock you into something that'll knock you into something that's instant death. Regardless of how careful you play, how good you are at the game and seeing what's ahead, it's still asking you to complete twelve levels with rigid, unforgiving accuracy.
And the "it's always your fault" crap does not really apply to Spelunky. Oh hey, something triggered an explosion in the shop while I was sixteen screens away from it. Now I have shopkeepers that can jump skyscrapers and one-hit kill me everywhere. So my fault. Oh, and I didn't find a compass or a jetpack before I got to the ice levels? That's 100% my fault. I should play better next time and get these items that didn't exist so I'm not making blind dives into, yup, instant death chasms.
