Enjoyable. Animations are good, as are sound effects. Certainly not for the squeamish, but the black humour comes through pretty clearly for me. Needs more by way of music, however. The slow walking pace (plus slow stand/duck motion during shooting sequences) doesn't seem to serve a gameplay purpose, beyond artificially increasing the difficulty. And it's really quite short -- two cutting sequences, two shooting sequences, and then it just ends.
So, it's rough, but a good way to spend ten minutes or so.
