Just wanted to update. I finally finished the first real level(1-1). Partially due to being busy and not really having much time, partially due to being distracted by other things, but part of that is the fact that it took a little while to grab me. IIRC, Dark Souls had much the same issue where I didn't start feeling it until at least around the point I was done with the Undead Burg(or maybe the undead parish?). So I finally broke my way out to the bridge over the huge door and then I started thinking....yes, this is the Dark Souls I remember....including the trap I should have spotted and didn't until I was flattened by a bunch of giant balls(and realized I could have triggered it before I went down that slope). And of course, that one dude with the red visor who I tried to kill several times before realizing maybe I'd best come back to him later. He seems to be guarding something important and the whole thing reminds me of the black knights from DS.
I also switched to the royalty class from Knight once I heard the benefits of it, so had to retrace my steps a little.
There is also a bit of frustration. The fact that once I figured out that I could upgrade my weapons/armor and level up at bonfires in Dark Souls, I got used to investing my souls in that to cut down on my risk when venturing into new areas. Demons Souls......well, I couldn't actually level up until I could talk to the maiden in black again and I needed hard/sharp stones to actually upgrade my weapons/armor. Now that I beat 1-1 I have a lot more options on how to spend my souls and not just accumulate them.
The other bit I'm not sure if it's me or the game. I've died more then once because for some reason the items in my active slots seem to change without warning. My shield will be unequipped, my sword will swap with my wand and vice versa and my stock of healing watercress will be replaced with turpentine. Which isn't bad but it is annoying, especially when I'm at close quarters and really need to stab, not range attack. I swear I'm not hitting the buttons on accident but maybe I'm wrong. Is this a known issue or does it sound like I have butterfingers?
One other then that stands out. The bit where the monumental explains things to you felt weird. It's appreciated, but coming from Dark Souls I'm used to everything being really implied, conveyed through cryptic dialogue and item descriptions, and suddenly I'm getting this cut-scene "Now I shall explain the history to you" lore dump. In any other game this would be normal. In a souls game it seems odd.
But yeah, this whole thing feels like Dark Souls 0, or rather, more Dark Souls content cut from that game. And yes, I realize it's more the other way around because Demons Soul came first.
