Of course, you know this means WAR! But what is it good for? I posit it will be good for lots of cartoon slapstick archetectural violence as Art and Pip get caught in an ever-worsening spiral of reprisal and counter-reprisal. This will continue until everything is destroyed.
Just as I forsaw, there can be no friendship in an open-ended sandbox game like this. In the end, there can be only one!
((P.S.: Quite shocked that I'm the first poster on this strip, given it went up yesterday!))
