Hi Krimzan_order,
I tried to post this on your Youtube, but for some reason I couldn't. In regards to the two passwords:
For the first one, it has to do with the hide and seek game. In each round, you find Flip the fish behind a certain door number. The door number order, that you find Flip behind, is the password.
For the second one, it has to do with the background. When you first get to the error scene it's one way, and then it changes so that some of the errors are different. Each number in the password, is the number of extra letters there are in each line. So, for instance, the first row has A's that just showed up. You'd count those and get the first number in the password.
I hope that makes sense. If not, let me know and I'll try and explain it better. Also, if you'd prefer I just say what each password is, let me know too.
