The starting code is, wait you think I'm telling you? 32 white cows on two red hills. What am I? (Hobbit reference.) For entering codes, just type the answer, no need for text-boxes. Another thing, don't keep holding it over the can, just drop it on the can, or else it doesn't work. Also all bugs totally intentional, so don't complain.
Go ahead and look in the code. I haven't been on for so long, even I'm looking in the code for the answer. Teeth
