Great!
I've always been a fan of gibbets, and I love how it serves a challenge and builds up suspense-Rescuing people before they die.
I like how you are forced to think, along with good graphics and a flow to the game, and no lag.
The only con about this is the unrealistic body movements of the humans after they are sliced down. Their body somehow resembles a ragdoll fashion, as their body is very limb and they don't do anything if they happen to land on their head.
Otherwise, I know it is sort of hard to make that advanced of an animation, but I think it was another sucess.
