I really loved the music in this game, that alone kept me pretty entertained.
I liked the idea of different formations, and they actually worked well. It would've been useful to see which button corresponds to what formation though. Trying to find the right one caused me some lives.
I don't get what this had to do with butchers, I didn't spot them anywhere in the actual game. O.o
Anyway this was a fun and short little game. :)
