very good
this reminds me of one of those desktop lemmings games where you spawn little people and then burn them to death and smash them on tyour desktop!
great work!
a suggestion i have is to make them say random things and make random noises. kinda like how you have them put up those little sad face signs and the "ohmygodi'monfire!" sign. little things like grunts when theyre hit, and coughing and sputtering when you douse them with a hose, or crying and pleading when you have torture them with something for a long time.
just the sadist in me i guess, but what the hey?
