This video is quite old. In fact, I recorded this playthrough two years ago but never uploaded it as accessible to everyone. After I was challenged in comments to one of my videos to do such playthrough, I decided to reupload it as public. The biggest problem with this record is sound: I don't know what happened to volume controls that time but to hear anything you'll have to increase volume greatly. Aside this, I consider this playthrough to be quite good and without too many mistakes (and still, the fourth boss battle is awfully played can't watch it even now).

I did not skip any of the cutscenes so the video is very long. If you do not want to watch them, here is exact time of the beginning of every act:
1:32 Act 1
4:04 Act 2
9:15 Act 3
15:50 Act 4
21:29 Act 5
26:35 Act 6
