This game is good. But also frustrating... in a weird way. I don't really think the game is that hard. I mean, I do die a lot, but almost all of my deaths are caused by A) Not knowing what to expect/first encounters, or B) Stupidity/rushing. Every time I slow myself down and concentrate on the battle I win. If anything, this game just shows me how impatient I am. The only thing I generally dislike are the level designs and environments. They don't look bad, they're just bland compared to today's standard. I guess this isn't really the point though since the levels are all designed for encounters, and less for exploration.
....bland level design? ehh...what? If anything - I think this game has some of the best level design I've seen in a game recently. Sure, there are a few exceptions - but as a whole, I think it's damn fine.
It's efficient, minimal full, almost every area has a purpose - it all ties in/interconnects in a smart way. Nice variation in environments, from the brown-sludge of Blight Town, to the gleeming city of Anor Londo, to the maze-like Catacombs.
For the most part, I think it has some of the most thoughtful level design I've seen recently.
Although I will agree with the game not being 'that hard' (it's still hard...but not as hard as others make it out to be). It just requires a certian patience / mindset that is lost with most gamers. People are used to charging in blindly, spamming their heaviest attack and being able to heal without consequence -- not so much in this game.
Little bit of patience and observation goes a long way, once you start to memorize things - you can rip through it very fast. Seriously, people can beat this game in around an hour -- still boggles me to watch them pull it off
and who knows how long they spent perfecting their game before they were able to accomplish that.
