Working on it.After several hours, I managed to polish off 4-1. Brilliant level design there. Now I'm back to 2-2, a level I really can't stand. Can't really use the dragon sword there (because of its fire effect) so I've switched to the weapon I picked up in 4-1, which is almost as good.
I'm actually a little scared of Dark Souls because the reviews I've read imply it's even harder and in some ways, cheaper. Demon's Souls strikes me as being difficult but (usually) fair.
Naw don't listen to that crap....both games have a way for any player to get by the bosses, not the least of which is to simply summon help....for demon's the whole game opens up once you finally kill the boss in 2.2. whatever you do, don't lose the soul you get there....with it, you can unlock better weapons choices and even some good spells etc. that you won't have access to otherwise....the soul of the boss in 4.1 can be converted to a pretty good weapon iirc....but you need Ed the blacksmith to do it for you and he wants the red hot demon soul first.
You may want to equip a bow and do the first part of 4.2.....lots of souls to accrue there
