I don't know the source material, but looking it up on the wikipedia makes both it and its author sound pretty interesting.
Most of the actions in the game seem superfluous to me. Including traversing the first half of the map and having to move many of the pieces which weren't travelling up to the guards; would that have made more sense if I'd read the source material?
I do like the art style, and I think it looks cool, particularly the handcuffs.
