Unable to complete
Shame, I was enjoying myself for a while until it came to changing the chalkboard. After I did that, everything halted. I finally checked the walkthrough because I had no idea what to do from there, but it seems he was supposed to have automatically said "barkeep" and requested a new drink a few seconds after you change the sign. Regardless, I'm a fan of the series and am sure had I not encountered this error I would have enjoyed it -- no zero from me.
