Really excellent submission.
I've been hoping someone would take on some Shakespeare for this jam, and you certainly did the bard's tale justice. Great animation, art coupled with the sound and music really capture the dark mood of the murderous plot. Best of all is the game design, especially the blood/ghost mechanic; most innovative use of source I've seen so far.
Hope you participate next time around too, looking forward to more ideas like this...Maybe somebody needs to do a Shakespeare gamejam?
