well if youve never played kitten canon...
its a disgustingly addicting flash game featuring a little orange kitty being shot out of a canon, if the kitty lands on a trampoline, torpedo held up by a balloon, or tnt, it is propelled forward.
however if its eaten by a venus fly trap, or lands on a spike strip (NOOO KITTY NOOO!) its game over. the object is to go extremely far.
you can angle the canon, and measure out the force of which it is shot out at.

please dont change the kitten part, thats what makes it so disgustingly addictive.
