Okay, I got every letter right and walked the longest way, so Marzia had to break a lot of doors down (which appearantly slows her down with every time) and I still couldn't put in the last friggin code in time. The last code has to be 0 or 10, otherwise Language Lil Puss seems impossible to me. This is kinda sad, because I think if I get this far on Boi difficulty, where I can actually use the shortcut, I could finally beat this level.

Maybe I can help. First I go to the area where the 9 door is and collect any Language notebooks there (It's easy to know which rooms there in thanks to the map here) and I put the codes on a separate online notepad so when I go back to wind up Phonty I can also put the codes in the elevator. Once I collect the 9th Language notebook, I go back and enter it into the elevator and wind Phonty for the last time. That way during the final chase I only have one code to remember and enter into the elevator. I also collect any Flashbangs and stamina items just to be safe.
