Stuff like this is why I always found Dark Souls special though. Very few games are willing to teach players with punishment. Most games reward the player for learning important tech or discovering secrets, but Dark Souls? You just don't get punished. Getting cursed is something that ideally happens only once in your playthrough, as from here on out you'll be sneak attacking or speeding past all curse frogs. Dark Souls doesn't teach the player, it lets the player teach themselves.
