Not bad, just needs a little work
This really wasn't that bad at all. The music set the perfect mood for the piece, the dialogue was decent, and the story seemed interesting enough (I'd watch the next video in the series, at the very least). The art was my biggest concern. Some images were very clear and beautifully drawn, but some of the others left a lot to be desired, particularly during the action scenes where it was difficult to tell what was happening. I did enjoy the fact that it was a simple black on white, though... it seemed to create the effect you were going for, and I'm sure the use of color would have ultimately proven to be a distraction.
You have room for improvement, and that's why I put my rating a little on the low side: I want to be able to rate the future installments as being better than this one (which I truly hope they will be).
