My time playing Dark Souls was well spent.
I really like this game. It took me 30 minutes and losing a few times, but I finally finished the game. And it felt great :D
I like the art style. The level design makes good use of the gameplay mechanics. The gameplay is smooth and well tuned. The death sound always scares me :D
The only thing I can recommend is showing how much time it took to complete the level (and maybe how many attempts were made).
Great game!
