I think I must have been fired 3 or 4 times before I understood. Then I got kicked out again a few times because I made a few careless mistakes :D
It took me a while to figure out the 1's and 0's, but then I was like “Ahah! But that's got to be it!” And then I didn't understand the numbers on the right. But I simply hadn't understood where I was supposed to write them. Anyway, the cryptic side works well :D
